4.1.3 "updatePaymentResource" interface
This API manage two different payment scenarios:
- To Process PSU identification, PSU authentication and explicit authorisation of transactions by using SCA, very similar in PIS and AIS services.
- To transfer data for SCA checks by the ASPSP only in case of an Embedded SCA Approach.
- To restart the payment execution flow after that the PSU has confirmed the payment after the
inspection of the transaction fees.

| payment-id | Resource Identification of the related payment initiation. |
| psuCredentials | PSU Credentials on the ASPSP system

| authenticationMethodId | The authentication method ID as provided by the ASPSP.
This field is mandatory if the operationto perform is an "updatePsuData" and the request is an Update psu data for select authentication. If this field is filled the psuCredentials field must be empty. |
| scaAuthenticationData | SCA authentication data, depending on the chosen authentication method. If the data is binary, then it is base64 encoded.
The field is mandatory if the selected operation to perform is a transactionAuthorisation. |

| psuCorporateDdType | The Payment Service User corporate identifier. Might be mandated by the ASPSP in addition if the PSU-Corporate-ID is contained. |
| chosenScaMethod | This data element is only contained in the response if the APSPS has chosen the
Embedded SCA Approach, if the PSU is already identified. |
| scaMethods | Might be contained, if several authentication methods are available. (name, type). |
| transactionStatus | Accepted values:
- ACCP |
| psuCredentials | The Payment Service User credentials on the ASPSP system |
| transactionFees | Can be used by the ASPSP to transport transaction fees relevant for the underlying payments. |
