4.2.3 "updatePeriodicPaymentResource" 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.
