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.
