! Registration must be completed by the TPP before being able to use AIS/PIS services.
The registration process is a simple POST to the registration endpoint. It contains the name of the TPP as it will be displayed to PSUs as well as the full certificate chains of the QWAC and the QSealC certificates.
Note that we do not allow QWAC and QSealC certificates to be the same, they must be different certificates.
The registration request must be authenticated with the QWAC and signed with the QSealC in the usual way.
Unifiedpost Payments will validate and store each certificate chain and verify the Issuer and the appropriate NCA register.
Once this is done the TPP will be activated and can issue AIS/PIS requests.
! For registration and when calling the services the full certificate chain of the QWAC certificate must be presented for Mutual TLS.
! Note that if either certificates changes the new certificates MUST both be registered before they can be used. Multiple QWAC/QSealC certificate pair may be active at one time.
