Update PSU data for payment initiation

This methods updates PSU data on the authorisation resource if needed.
It may authorise a payment 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 payment initiation services 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
