A list of hyperlinks to be recognised by the TPP. The actual hyperlinks used in the response depend on the dynamical decisions of the ASPSP when processing the request.

Remark: All links can be relative or full links, to be decided by the ASPSP.

Type of links admitted in this response, (further links might be added for ASPSP defined extensions):

'scaRedirect': In case of an SCA Redirect Approach, the ASPSP is transmitting the link to which to redirect the PSU browser.
'scaOAuth': In case of a SCA OAuth2 Approach, the ASPSP is transmitting the URI where the configuration of the Authorisation Server can be retrieved. The configuration follows the OAuth 2.0 Authorisation Server Metadata specification.
'startAuthorisation': In case, where an explicit start of the transaction authorisation is needed, but no more data needs to be updated (no authentication method to be selected, no PSU identification nor PSU authentication data to be uploaded).
'startAuthorisationWithPsuIdentification': The link to the authorisation end-point, where the authorisation sub-resource has to be generated while uploading the PSU identification data.
'startAuthorisationWithPsuAuthentication': The link to the authorisation end-point, where the authorisation sub-resource has to be generated while uploading the PSU authentication data.
- 'startAuthorisationWithEncryptedPsuAuthentication': Same as startAuthorisactionWithPsuAuthentication where the authentication data need to be encrypted on application layer in uploading.
'startAuthorisationWithAuthenticationMethodSelection': The link to the authorisation end-point, where the authorisation sub-resource has to be generated while selecting the authentication method. This link is contained under exactly the same conditions as the data element "scaMethods"
'startAuthorisationWithTransactionAuthorisation': The link to the authorisation end-point, where the authorisation sub-resource has to be generated while authorising the transaction e.g. by uploading an OTP received by SMS.
'self': The link to the payment initiation resource created by this request. This link can be used to retrieve the resource data.
'status': The link to retrieve the transaction status of the payment initiation.
'scaStatus': The link to retrieve the scaStatus of the corresponding authorisation sub-resource. This link is only contained, if an authorisation sub-resource has been already created.
