Dear partner,

We want to inform you that in September 2021 (the exact date will be communicated later) we will upgrade our APIs from version 5 to version 7. This evolution will introduce some breaking changes : the main one is about a new SCA Oauth2 response in the consent creation or when submitting a payment submission.

To know more about this breaking change, we kindly invite you to read the dedicated section on our developer portal : HowTo / "13 - Build your authorize URL".

To give you a quick overview, here is some of the others breaking changes : frequency codes and standing order data model, the data type Max512 text has been adapted to Max500 text, AIS consent scope "availableAccountsWithBalances" has been corrected to "availableAccountsWithBalance", changes in the creditor adress (street→ streetname) and validation changes on the incomling TPP headers.

Please note that you can already test the breaking changes by using the new version of the sandbox available on the developer portal.

Don’t hesitate to contact us if you have any question
