Amazon Simple Storage Service

This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts. To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty. For information about permissions required to use the multipart upload, see Multipart Upload and Permissions. The following operations are related to AbortMultipartUpload: CreateMultipartUpload UploadPart CompleteMultipartUpload ListParts ListMultipartUploads

Completes a multipart upload by assembling previously uploaded parts. You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded. Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. Because a request could fail after the initial 200 OK response has been sent, it is important that you check the response body to determine whether the request succeeded. Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices. You cannot use Content-Type: application/x-www-form-urlencoded with Complete Multipart Upload requests. Also, if you do not provide a Content-Type header, CompleteMultipartUpload returns a 200 OK response. For more information about multipart uploads, see Uploading Objects Using Multipart Upload. For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions. CompleteMultipartUpload has the following special errors: Error code: EntityTooSmall Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part. 400 Bad Request Error code: InvalidPart Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified entity tag might not have matched the part's entity tag. 400 Bad Request Error code: InvalidPartOrder Description: The list of parts was not in ascending order. The parts list must be specified in order by part number. 400 Bad Request Error code: NoSuchUpload Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed. 404 Not Found The following operations are related to CompleteMultipartUpload: CreateMultipartUpload UploadPart AbortMultipartUpload ListParts ListMultipartUploads

Creates a copy of an object that is already stored in Amazon S3. You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API. All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication. Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account. A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately. If the copy is successful, you receive a response with information about the copied object. If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body. The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing. Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration. Metadata When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs. To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide. For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3. x-amz-copy-source-if Headers To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters: x-amz-copy-source-if-match x-amz-copy-source-if-none-match x-amz-copy-source-if-unmodified-since x-amz-copy-source-if-modified-since If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data: x-amz-copy-source-if-match condition evaluates to true x-amz-copy-source-if-unmodified-since condition evaluates to false If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code: x-amz-copy-source-if-none-match condition evaluates to false x-amz-copy-source-if-modified-since condition evaluates to true All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. Server-side encryption When you perform a CopyObject operation, you can optionally use the appropriate encryption-related headers to encrypt the object using server-side encryption with Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS) or a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption. If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide. Access Control List (ACL)-Specific Request Headers When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API. If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide. If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner. Checksums When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header. Storage Class Options You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 User Guide. Versioning By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource. If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response. If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null. If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject. The following operations are related to CopyObject: PutObject GetObject For more information, see Copying Objects.

Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner. Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules. If you want to create an Amazon S3 on Outposts bucket, see Create Bucket. By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket. If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets. Access control lists (ACLs) When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket. If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide. There are two ways to grant the appropriate permissions using the request headers. Specify a canned ACL using the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL. Specify access permissions explicitly using the x-amz-grant-read, x-amz-grant-write, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview. You specify each grantee as a type=value pair, where the type is one of the following: id – if the value specified is the canonical user ID of an Amazon Web Services account uri – if you are granting permissions to a predefined group emailAddress – if the value specified is the email address of an Amazon Web Services account Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions: US East (N. Virginia) US West (N. California) US West (Oregon) Asia Pacific (Singapore) Asia Pacific (Sydney) Asia Pacific (Tokyo) Europe (Ireland) South America (São Paulo) For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference. For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata: x-amz-grant-read: id="11112222333", id="444455556666" You can use either a canned ACL or specify access permissions explicitly. You cannot do both. Permissions In addition to s3:CreateBucket, the following permissions are required when your CreateBucket includes specific headers: ACLs - If your CreateBucket request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both s3:CreateBucket and s3:PutBucketAcl permissions are needed. If the ACL the CreateBucket request is private or doesn't specify any ACLs, only s3:CreateBucket permission is needed. Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request, s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required. S3 Object Ownership - If your CreateBucket request includes the the x-amz-object-ownership header, s3:PutBucketOwnershipControls permission is required. The following operations are related to CreateBucket: PutObject DeleteBucket

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request. For more information about multipart uploads, see Multipart Upload Overview. If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy. For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions. For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4). After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload. You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use Amazon Web Services KMS keys or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload. To perform a multipart upload with encryption using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions in the Amazon S3 User Guide. If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role. For more information, see Protecting Data Using Server-Side Encryption. Access Permissions When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers: Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL. Specify access permissions explicitly with the x-amz-grant-read, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview. You can use either a canned ACL or specify access permissions explicitly. You cannot do both. Server-Side- Encryption-Specific Request Headers You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use Amazon Web Services managed encryption keys or provide your own encryption key. Use encryption keys managed by Amazon S3 or customer managed key stored in Amazon Web Services Key Management Service (Amazon Web Services KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request. x-amz-server-side-encryption x-amz-server-side-encryption-aws-kms-key-id x-amz-server-side-encryption-context If you specify x-amz-server-side-encryption:aws:kms, but don't provide x-amz-server-side-encryption-aws-kms-key-id, Amazon S3 uses the Amazon Web Services managed key in Amazon Web Services KMS to protect the data. All GET and PUT requests for an object protected by Amazon Web Services KMS fail if you don't make them with SSL or by using SigV4. For more information about server-side encryption with KMS key (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys. Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request. x-amz-server-side-encryption-customer-algorithm x-amz-server-side-encryption-customer-key x-amz-server-side-encryption-customer-key-MD5 For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys. Access-Control-List (ACL)-Specific Request Headers You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs. With this operation, you can grant access permissions using one of the following two methods: Specify a canned ACL (x-amz-acl) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL. Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview. In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use: x-amz-grant-read x-amz-grant-write x-amz-grant-read-acp x-amz-grant-write-acp x-amz-grant-full-control You specify each grantee as a type=value pair, where the type is one of the following: id – if the value specified is the canonical user ID of an Amazon Web Services account uri – if you are granting permissions to a predefined group emailAddress – if the value specified is the email address of an Amazon Web Services account Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions: US East (N. Virginia) US West (N. California) US West (Oregon) Asia Pacific (Singapore) Asia Pacific (Sydney) Asia Pacific (Tokyo) Europe (Ireland) South America (São Paulo) For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference. For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata: x-amz-grant-read: id="11112222333", id="444455556666" The following operations are related to CreateMultipartUpload: UploadPart CompleteMultipartUpload AbortMultipartUpload ListParts ListMultipartUploads

Deletes the S3 bucket. All objects (including all object versions and delete markers) in the bucket must be deleted before the bucket itself can be deleted. Related Resources CreateBucket DeleteObject

Deletes an analytics configuration for the bucket (specified by the analytics configuration ID). To use this operation, you must have permissions to perform the s3:PutAnalyticsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources. For information about the Amazon S3 analytics feature, see Amazon S3 Analytics – Storage Class Analysis. The following operations are related to DeleteBucketAnalyticsConfiguration: GetBucketAnalyticsConfiguration ListBucketAnalyticsConfigurations PutBucketAnalyticsConfiguration

Deletes the cors configuration information set for the bucket. To use this operation, you must have permission to perform the s3:PutBucketCORS action. The bucket owner has this permission by default and can grant this permission to others. For information about cors, see Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide. Related Resources: PutBucketCors RESTOPTIONSobject

This implementation of the DELETE action removes default encryption from the bucket. For information about the Amazon S3 default encryption feature, see Amazon S3 Default Bucket Encryption in the Amazon S3 User Guide. To use this operation, you must have permissions to perform the s3:PutEncryptionConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide. Related Resources PutBucketEncryption GetBucketEncryption

Deletes the S3 Intelligent-Tiering configuration from the specified bucket. The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities. The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class. For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects. Operations related to DeleteBucketIntelligentTieringConfiguration include: GetBucketIntelligentTieringConfiguration PutBucketIntelligentTieringConfiguration ListBucketIntelligentTieringConfigurations

Deletes an inventory configuration (identified by the inventory ID) from the bucket. To use this operation, you must have permissions to perform the s3:PutInventoryConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources. For information about the Amazon S3 inventory feature, see Amazon S3 Inventory. Operations related to DeleteBucketInventoryConfiguration include: GetBucketInventoryConfiguration PutBucketInventoryConfiguration ListBucketInventoryConfigurations

Deletes the lifecycle configuration from the specified bucket. Amazon S3 removes all the lifecycle configuration rules in the lifecycle subresource associated with the bucket. Your objects never expire, and Amazon S3 no longer automatically deletes any objects on the basis of rules contained in the deleted lifecycle configuration. To use this operation, you must have permission to perform the s3:PutLifecycleConfiguration action. By default, the bucket owner has this permission and the bucket owner can grant this permission to others. There is usually some time lag before lifecycle configuration deletion is fully propagated to all the Amazon S3 systems. For more information about the object expiration, see Elements to Describe Lifecycle Actions. Related actions include: PutBucketLifecycleConfiguration GetBucketLifecycleConfiguration

Deletes a metrics configuration for the Amazon CloudWatch request metrics (specified by the metrics configuration ID) from the bucket. Note that this doesn't include the daily storage metrics. To use this operation, you must have permissions to perform the s3:PutMetricsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources. For information about CloudWatch request metrics for Amazon S3, see Monitoring Metrics with Amazon CloudWatch. The following operations are related to DeleteBucketMetricsConfiguration: GetBucketMetricsConfiguration PutBucketMetricsConfiguration ListBucketMetricsConfigurations Monitoring Metrics with Amazon CloudWatch

Removes OwnershipControls for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketOwnershipControls permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy. For information about Amazon S3 Object Ownership, see Using Object Ownership. The following operations are related to DeleteBucketOwnershipControls: GetBucketOwnershipControls PutBucketOwnershipControls

This implementation of the DELETE action uses the policy subresource to delete the policy of a specified bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account to use this operation. If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error. As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action. For more information about bucket policies, see Using Bucket Policies and UserPolicies. The following operations are related to DeleteBucketPolicy CreateBucket DeleteObject

Deletes the replication configuration from the bucket. To use this operation, you must have permissions to perform the s3:PutReplicationConfiguration action. The bucket owner has these permissions by default and can grant it to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources. It can take a while for the deletion of a replication configuration to fully propagate. For information about replication configuration, see Replication in the Amazon S3 User Guide. The following operations are related to DeleteBucketReplication: PutBucketReplication GetBucketReplication

Deletes the tags from the bucket. To use this operation, you must have permission to perform the s3:PutBucketTagging action. By default, the bucket owner has this permission and can grant this permission to others. The following operations are related to DeleteBucketTagging: GetBucketTagging PutBucketTagging

This action removes the website configuration for a bucket. Amazon S3 returns a 200 OK response upon successfully deleting a website configuration on the specified bucket. You will get a 200 OK response if the website configuration you are trying to delete does not exist on the bucket. Amazon S3 returns a 404 response if the bucket specified in the request does not exist. This DELETE action requires the S3:DeleteBucketWebsite permission. By default, only the bucket owner can delete the website configuration attached to a bucket. However, bucket owners can grant other users permission to delete the website configuration by writing a bucket policy granting them the S3:DeleteBucketWebsite permission. For more information about hosting websites, see Hosting Websites on Amazon S3. The following operations are related to DeleteBucketWebsite: GetBucketWebsite PutBucketWebsite

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful. To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker, to true. If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS. For more information about MFA Delete, see Using MFA Delete. To see sample requests that use versioning, see Sample Request. You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions. The following action is related to DeleteObject: PutObject

Removes the entire tag set from the specified object. For more information about managing object tags, see Object Tagging. To use this operation, you must have permission to perform the s3:DeleteObjectTagging action. To delete tags of a specific object version, add the versionId query parameter in the request. You will need permission for the s3:DeleteObjectVersionTagging action. The following operations are related to DeleteBucketMetricsConfiguration: PutObjectTagging GetObjectTagging

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead. The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted. The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body. When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete. Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit. The following operations are related to DeleteObjects: CreateMultipartUpload UploadPart CompleteMultipartUpload ListParts AbortMultipartUpload

Removes the PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources. The following operations are related to DeletePublicAccessBlock: Using Amazon S3 Block Public Access GetPublicAccessBlock PutPublicAccessBlock GetBucketPolicyStatus

This implementation of the GET action uses the accelerate subresource to return the Transfer Acceleration state of a bucket, which is either Enabled or Suspended. Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to and from Amazon S3. To use this operation, you must have permission to perform the s3:GetAccelerateConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide. You set the Transfer Acceleration state of an existing bucket to Enabled or Suspended by using the PutBucketAccelerateConfiguration operation. A GET accelerate request does not return a state value for a bucket that has no transfer acceleration state. A bucket has no Transfer Acceleration state if a state has never been set on the bucket. For more information about transfer acceleration, see Transfer Acceleration in the Amazon S3 User Guide. Related Resources PutBucketAccelerateConfiguration

This implementation of the GET action uses the acl subresource to return the access control list (ACL) of a bucket. To use GET to return the ACL of the bucket, you must have READ_ACP access to the bucket. If READ_ACP permission is granted to the anonymous user, you can return the ACL of the bucket without using an authorization header. If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide. Related Resources ListObjects

This implementation of the GET action returns an analytics configuration (identified by the analytics configuration ID) from the bucket. To use this operation, you must have permissions to perform the s3:GetAnalyticsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

Gets the S3 Intelligent-Tiering configuration from the specified bucket. The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities. The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class. For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

The following operations are related to GetBucketTagging: PutBucketTagging DeleteBucketTagging

Returns the versioning state of a bucket. To retrieve the versioning state of a bucket, you must be the bucket owner. This implementation also returns the MFA Delete status of the versioning state. If the MFA Delete status is enabled, the bucket owner must use an authentication device to change the versioning state of the bucket. The following operations are related to GetBucketVersioning: GetObject PutObject DeleteObject

Returns the website configuration for a bucket. To host website on Amazon S3, you can configure a bucket as website by adding a website configuration. For more information about hosting websites, see Hosting Websites on Amazon S3. This GET action requires the S3:GetBucketWebsite permission. By default, only the bucket owner can read the bucket website configuration. However, bucket owners can allow other users to read the website configuration by writing a bucket policy granting them the S3:GetBucketWebsite permission. The following operations are related to DeleteBucketWebsite: DeleteBucketWebsite PutBucketWebsite

Retrieves objects from Amazon S3. To use GET, you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header. An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg, you can name it photos/2006/February/sample.jpg. To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the resource as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the resource as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification. For more information about returning the ACL of an object, see GetObjectAcl. If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects. Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error. If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers: x-amz-server-side-encryption-customer-algorithm x-amz-server-side-encryption-customer-key x-amz-server-side-encryption-customer-key-MD5 For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys). Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object. Permissions You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission. If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error. If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error. Versioning By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource. If you supply a versionId, you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission. If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response. For more information about versioning, see PutBucketVersioning. Overriding Response Header Values There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request. You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition, and Content-Encoding. To override these header values in the GET response, you use the following request parameters. You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request. response-content-type response-content-language response-expires response-cache-control response-content-disposition response-content-encoding Additional Considerations about Request Headers If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true, and; If-Unmodified-Since condition evaluates to false; then, S3 returns 200 OK and the data requested. If both of the If-None-Match and If-Modified-Since headers are present in the request as follows: If-None-Match condition evaluates to false, and; If-Modified-Since condition evaluates to true; then, S3 returns 304 Not Modified response code. For more information about conditional requests, see RFC 7232. The following operations are related to GetObject: ListBuckets GetObjectAcl

Returns the access control list (ACL) of an object. To use this operation, you must have s3:GetObjectAcl permissions or READ_ACP access to the object. For more information, see Mapping of ACL permissions and access policy permissions in the Amazon S3 User Guide This action is not supported by Amazon S3 on Outposts. Versioning By default, GET returns ACL information about the current version of an object. To return ACL information about a different version, use the versionId subresource. If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide. The following operations are related to GetObjectAcl: GetObject GetObjectAttributes DeleteObject PutObject

Retrieves all the metadata from an object without returning the object itself. This action is useful if you're interested only in an object's metadata. To use GetObjectAttributes, you must have READ access to the object. GetObjectAttributes combines the functionality of GetObjectAcl, GetObjectLegalHold, GetObjectLockConfiguration, GetObjectRetention, GetObjectTagging, HeadObject, and ListParts. All of the data returned with each of those individual calls can be returned with a single call to GetObjectAttributes. If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers: x-amz-server-side-encryption-customer-algorithm x-amz-server-side-encryption-customer-key x-amz-server-side-encryption-customer-key-MD5 For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide. Encryption request headers, such as x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with Amazon Web Services KMS keys stored in Amazon Web Services Key Management Service (SSE-KMS) or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). If your object does use these types of keys, you'll get an HTTP 400 Bad Request error. The last modified property in this case is the creation date of the object. Consider the following when using request headers: If both of the If-Match and If-Unmodified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 200 OK and the data requested: If-Match condition evaluates to true. If-Unmodified-Since condition evaluates to false. If both of the If-None-Match and If-Modified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 304 Not Modified: If-None-Match condition evaluates to false. If-Modified-Since condition evaluates to true. For more information about conditional requests, see RFC 7232. Permissions The permissions that you need to use this operation depend on whether the bucket is versioned. If the bucket is versioned, you need both the s3:GetObjectVersion and s3:GetObjectVersionAttributes permissions for this operation. If the bucket is not versioned, you need the s3:GetObject and s3:GetObjectAttributes permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide. If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission. If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found ("no such key") error. If you don't have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden ("access denied") error. The following actions are related to GetObjectAttributes: GetObject GetObjectAcl GetObjectLegalHold GetObjectLockConfiguration GetObjectRetention GetObjectTagging HeadObject ListParts

Gets an object's current legal hold status. For more information, see Locking Objects. This action is not supported by Amazon S3 on Outposts. The following action is related to GetObjectLegalHold: GetObjectAttributes
