To use Account Information Services, the initiating party has to identify the Payment Service User (PSU) so that a consent provided by the PSU can be used in subsequent Account Information Service calls. In the TPP solution, this Id is known as the ‘PsuId’, this PsuId can be:
• Provided by the Initiating party
• or generated by the TPP solution, using the optional PSU management service
The PSU management service can reduce the amount of registration required on the Initiating party side. In the future, the PSU management service will be extended with the ability to store payment related preferences.
The APIs listed here will allow you to proceed with PSU’s Management, including Posting, Updating and Deleting of PSUs.
