La Banque Postale has developed APIs in order to comply with the requirements of the delegated Commission Delegated Regulation (EU) 2018/389 of 27 November 2017 (RTS) and thus enable TPP to offer their service.

The status of La Banque Postale's API is as follows:

  • The confirmation on the availability of funds API (CBPII) is compliant.
  • The account information API (AISP) is compliant.
  • The payment initiation API (PISP) is compliant with the following features: SCT inst, SCT, standing orders and international payments.

 

As part of its commitment to quality, LA BANQUE POSTALE's Open-Banking team is carrying out a satisfaction survey among its TPP users to evaluate and improve its APIs service offering and the quality of its support service.

We value your opinion.

 

Thank you in advance for your feedback!

 

28/05/2025 - Important : Your fallback API is evolving. 
Due to a tightening of security rules La Banque Postale informs you of a change on the fallback solution used for authenticated webscrapping.
In order to allow the TPP to be exempted from new strong authentications in webscrapping, the following principles must be respected:

  • The initial call to the 4 “/api/fallback” endpoints remains unchanged.
  • The two headers “Authorization” and “DN” must be reused when redirecting to the customer login screen (Online Banking login / Password). Without these headers, the connection will be rejected. If both headers are supplied correctly, the TPP authenticated via the fallback API will be exempt from FirstSeen authentication.

The implementation of this feature is expected to take a few weeks. Please do not hesitate to contact us should you require any further clarification or specific support.

 

16/10/2024 - Important : PISP API version 1 (STET 1.4) has been deprecated due to the release of version 2 (STET 1.6). As a result, we kindly request that all users migrate to v2 before April 30st, 2025, as v1 will be removed on that date. We apologize for any inconvenience this may cause and would like to remind you that version 2 offers improved functionality and better performance. If you have any questions or need assistance with the migration process, please don't hesitate to contact our support team. Thank you for your cooperation and understanding.
