BNP Paribas Fortis API: frequently asked questions
Does BNP Paribas Fortis have a public API?
Yes. BNP Paribas Fortis publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII), plus premium APIs beyond that baseline. Registration and documentation live on its developer portal at https://developer.bnpparibasfortis.com.
Does BNP Paribas Fortis offer an API sandbox?
Yes. Sandbox access is available but not self-service, so you go through the bank to get in.
Which open banking standard does the BNP Paribas Fortis API use?
STET (France): the open-banking API standard used by French (and some Belgian) banks. Two banks on the same standard can still differ in the details, so read the bank's own documentation before you build.
How do you authenticate with the BNP Paribas Fortis API?
OAuth 2.0, with redirect SCA for the customer consent step. Production access to the regulated endpoints also means registering as a licensed third-party provider with the bank.
Does BNP Paribas Fortis offer premium APIs beyond PSD2?
Yes. We have recorded 5 premium categories on BNP Paribas Fortis: real-time balances, statement reporting, bulk payments, payment tracking and pooling & sweeping. These sit above the regulated PSD2 baseline and are the ones corporate treasury teams tend to care about.
Which countries does the BNP Paribas Fortis API cover?
Belgium.
Is the BNP Paribas Fortis API free to use?
Banks generally do not charge licensed third-party providers for the regulated open banking endpoints, which is the point of the mandate. Premium APIs above that baseline are commercial products priced by the bank. BankSnipe does not track pricing, so confirm it with the bank.
How mature is the BNP Paribas Fortis API?
BankSnipe scores it 5 out of 5 (Mature). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated PSD2 baseline.
