Account API

Access account balances and transaction history of Belfius customers in total security.


Account balance Sandboxed

Provides the possibility to view the current or previous balance of an account.

Transaction history Sandboxed

Provides the possibility to view a list of transactions for an account and filters by date, type and recurrence.

How does it work?


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


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


The TPP application 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.

Directions for use

Access to the production system is granted on a case-by-case basis. Approval will be given subject to complying with user rules determined by Belfius in line with the European PSD2 directive. More information.
