Crédit Mutuel Alliance Fédérale and CIC run structurally identical STET-based PSD2 portals with all three roles and sandboxes; authentication uses mutual TLS plus OAuth2 and HTTP message signatures.
Crédit Mutuel (incl. CIC) API: frequently asked questions
Does Crédit Mutuel (incl. CIC) have a public API?
Yes. Crédit Mutuel (incl. CIC) publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Registration and documentation live on its developer portal at https://oauth2.creditmutuel.fr/en/devportal/index.html.
Does Crédit Mutuel (incl. CIC) offer an API sandbox?
Yes. The sandbox is self-service, so you can sign up and start calling it without a commercial agreement in place.
Which open banking standard does the Crédit Mutuel (incl. CIC) 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 Crédit Mutuel (incl. CIC) 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 Crédit Mutuel (incl. CIC) offer premium APIs beyond PSD2?
Not that we have recorded. Crédit Mutuel (incl. CIC)'s listing covers the regulated PSD2 baseline only.
Which countries does the Crédit Mutuel (incl. CIC) API cover?
France.
Is the Crédit Mutuel (incl. CIC) 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 Crédit Mutuel (incl. CIC) API?
BankSnipe scores it 4 out of 5 (Established). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated PSD2 baseline.
