How does it work?


A Third Party Provider (TPP) registers an application with Belfius.


A Belfius or Banx customer requests to see his account balance or transaction history using the TPP application.


The TPP calls the AIS APIs, providing an access token (which was received through the Consent flow).

All set

The customer can view his account balance and transaction history on the TPP application.
