Payment cancellation request This method initiates the cancellation of a payment. Depending on the payment-service, the payment-product and the ASPSP's implementation, this TPP call might be sufficient to cancel a payment. If an authorisation of the payment cancellation is mandated by the ASPSP, a corresponding hyperlink will be contained in the response message. Cancels the addressed payment with resource identification paymentId if applicable to the payment-service, payment-product and received in product related timelines (e.g. before end of business day for scheduled payments of the last business day before the scheduled execution day). The response to this DELETE command will tell the TPP whether the * access method was rejected, * access method was successful, or * access method is generally applicable, but further authorisation processes are needed.

Confirmation of funds request Creates a confirmation of funds request at the ASPSP. Checks whether a specific amount is available at point of time of the request on an account linked to a given tuple card issuer(TPP)/card number, or addressed by IBAN and TPP respectively. If the related extended services are used a conditional Consent-ID is contained in the header. This field is contained but commented out in this specification.

Create consent This method create a consent resource, defining access rights to dedicated accounts of a given PSU-ID. These accounts are addressed explicitly in the method as parameters as a core function. **Side Effects** When this consent request is a request where the "recurringIndicator" equals "true", and if it exists already a former consent for recurring access on account information for the addressed PSU, then the former consent automatically expires as soon as the new consent request is authorised by the PSU. Optional Extension: As an option, an ASPSP might optionally accept a specific access right on the access on all PSD2 related services for all available accounts. As another option an ASPSP might optionally also accept a command, where only access rights are inserted without mentioning the addressed account. The relation to accounts is then handled afterwards between PSU and ASPSP. This option is not supported for the Embedded SCA Approach. As a last option, an ASPSP might in addition accept a command with access rights * to see the list of available payment accounts or * to see the list of available payment accounts with balances.

Create a signing basket resource for authorising several transactions with one SCA method. The resource identifications of these transactions are contained in the payload of this access method

Delete Consent The TPP can delete an account information consent object if needed.

Delete the signing basket structure as long as no (partial) authorisation has yet been applied. The undlerying transactions are not affected by this deletion. Remark: The signing basket as such is not deletable after a first (partial) authorisation has been applied. Nevertheless, single transactions might be cancelled on an individual basis on the XS2A interface.

Read account list Read the identifiers of the available payment account together with booking balance information, depending on the consent granted. It is assumed that a consent of the PSU to this access is already given and stored on the ASPSP system. The addressed list of accounts depends then on the PSU ID and the stored consent addressed by consentId, respectively the OAuth2 access token. Returns all identifiers of the accounts, to which an account access has been granted to through the /consents endpoint by the PSU. In addition, relevant information about the accounts and hyperlinks to corresponding account information resources are provided if a related consent has been already granted. Remark: Note that the /consents endpoint optionally offers to grant an access on all available payment accounts of a PSU. In this case, this endpoint will deliver the information about all available payment accounts of the PSU at this ASPSP.

Read balance Reads account data from a given account addressed by "account-id". **Remark:** This account-id can be a tokenised identification due to data protection reason since the path information might be logged on intermediary servers within the ASPSP sphere. This account-id then can be retrieved by the "Get account list" call. The account-id is constant at least throughout the lifecycle of a given consent.

Get consent authorisation sub-resources request Return a list of all authorisation subresources IDs which have been created. This function returns an array of hyperlinks to all generated authorisation sub-resources.

Get consent request Returns the content of an account information consent object. This is returning the data for the TPP especially in cases, where the consent was directly managed between ASPSP and PSU e.g. in a redirect SCA Approach.

Read the SCA status of the consent authorisation This method returns the SCA status of a consent initiation's authorisation sub-resource.

Consent status request Read the status of an account information consent resource.

Read the SCA status of the payment cancellation's authorisation This method returns the SCA status of a payment initiation's authorisation sub-resource.

Get payment information Returns the content of a payment object

Get payment initiation authorisation sub-resources request Read a list of all authorisation subresources IDs which have been created. This function returns an array of hyperlinks to all generated authorisation sub-resources.

Will deliver an array of resource identifications to all generated cancellation authorisation sub-resources Retrieve a list of all created cancellation authorisation sub-resources.

Read the SCA status of the payment authorisation This method returns the SCA status of a payment initiation's authorisation sub-resource.

Payment initiation status request Check the transaction status of a payment initiation.

Returns the content of an signing basket object Returns the content of a signing basket object.

Get signing basket authorisation sub-resources request Read a list of all authorisation subresources IDs which have been created. This function returns an array of hyperlinks to all generated authorisation sub-resources.

Read the SCA status of the signing basket authorisation This method returns the SCA status of a signing basket's authorisation sub-resource.

Read the status of the signing basket Returns the status of a signing basket object.

Read transaction details Reads transaction details from a given transaction addressed by "transactionId" on a given account addressed by "account-id". This call is only available on transactions as reported in a JSON format. **Remark:** Please note that the PATH might be already given in detail by the corresponding entry of the response of the "Read Transaction List" call within the _links subfield.

Read transaction list of an account Read transaction reports or transaction lists of a given account ddressed by "account-id", depending on the steering parameter "bookingStatus" together with balances. For a given account, additional parameters are e.g. the attributes "dateFrom" and "dateTo". The ASPSP might add balance information, if transaction lists without balances are not supported.

Payment initiation request This method is used to initiate a payment at the ASPSP. ## Variants of payment initiation requests This method to initiate a payment initiation at the ASPSP can be sent with either a JSON body or an pain.001 body depending on the payment product in the path. There are the following **payment products**: - Payment products with payment information in *JSON* format: - ***domestic-swiss-credit-transfers-isr*** - ***domestic-swiss-credit-transfers*** - ***domestic-swiss-credit-transfers-qr*** - ***domestic-swiss-foreign-credit-transfers*** - ***swiss-sepa-credit-transfers*** - ***swiss-cross-border-credit-transfers*** - Payment products with payment information in *SIX pain.001* XML format: - ***pain.001-sepa-credit-transfers*** - ***pain.001-cross-border-credit-transfers*** - ***pain.001-swiss-six-credit-transfers*** Furthermore the request body depends on the **payment-service**: * ***payments***: A single payment initiation request. * ***bulk-payments***: A collection of several payment initiation requests. In case of a *pain.001* message there are more than one payments contained in the *pain.001 message. In case of a *JSON* there are several JSON payment blocks contained in a joining list. * ***periodic-payments***: Create a standing order initiation resource for recurrent i.e. periodic payments addressable under {paymentId} with all data relevant for the corresponding payment product and the execution of the standing order contained in a JSON body. This is the first step in the API to initiate the related recurring/periodic payment. ## Single and mulitilevel SCA Processes The payment initiation requests are independent from the need of one or multilevel SCA processing, i.e. independent from the number of authorisations needed for the execution of payments. But the response messages are specific to either one SCA processing or multilevel SCA processing. For payment initiation with multilevel SCA, this specification requires an explicit start of the authorisation, i.e. links directly associated with SCA processing like 'scaRedirect' or 'scaOAuth' cannot be contained in the response message of a Payment Initation Request for a payment, where multiple authorisations are needed. Also if any data is needed for the next action, like selecting an SCA method is not supported in the response, since all starts of the multiple authorisations are fully equal. In these cases, first an authorisation sub-resource has to be generated following the 'startAuthorisation' link.

Read account details Reads details about an account, with balances where required. It is assumed that a consent of the PSU to this access is already given and stored on the ASPSP system. The addressed details of this account depends then on the stored consent addressed by consentId, respectively the OAuth2 access token. **NOTE:** The account-id can represent a multicurrency account. In this case the currency code is set to "XXX". Give detailed information about the addressed account. Give detailed information about the addressed account together with balance information

Start the authorisation process for a consent Create an authorisation sub-resource and start the authorisation process of a consent. The message might in addition transmit authentication and authorisation related data. his method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the consent. The ASPSP might make the usage of this access method unnecessary, since the related authorisation resource will be automatically created by the ASPSP after the submission of the consent data with the first POST consents call. The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource. This applies in the following scenarios: * The ASPSP has indicated with an 'startAuthorisation' hyperlink in the preceding Payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms: * 'startAuthorisationWithPsuIdentfication', * 'startAuthorisationWithPsuAuthentication' * 'startAuthorisationWithEncryptedPsuAuthentication' * 'startAuthorisationWithAuthentciationMethodSelection' * The related payment initiation cannot yet be executed since a multilevel SCA is mandated. * The ASPSP has indicated with an 'startAuthorisation' hyperlink in the preceding payment cancellation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms as indicated above. * The related payment cancellation request cannot be applied yet since a multilevel SCA is mandate for executing the cancellation. * The signing basket needs to be authorised yet.

Update PSU Data for consents This method update PSU data on the consents resource if needed. It may authorise a consent within the Embedded SCA Approach where needed. Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication. There are several possible update PSU data requests in the context of a consent request if needed, which depends on the SCA approach: * Redirect SCA Approach: A specific Update PSU data request is applicable for * the selection of authentication methods, before choosing the actual SCA approach. * Decoupled SCA Approach: A specific update PSU data request is only applicable for * adding the PSU Identification, if not provided yet in the payment initiation request or the Account Information Consent Request, or if no OAuth2 access token is used, or * the selection of authentication methods. * Embedded SCA Approach: The Update PSU data request might be used * to add credentials as a first factor authentication data of the PSU and * to select the authentication method and * transaction authorisation. The SCA Approach might depend on the chosen SCA method. For that reason, the following possible update PSU data request can apply to all SCA approaches: * Select an SCA method in case of several SCA methods are available for the customer. There are the following request types on this access path: * Update PSU identification * Update PSU authentication * Select PSU autorization method WARNING: This method needs a reduced header, therefore many optional elements are not present.
