Experience with our

Getting to know APIs?

APIs are interfaces for electronic data exchange. They allow efficient and secure access to systems and services of organisations in order to connect business processes and thus create value chains across organisations.

Fidor offers APIs for:
Banking | Payment | Credit | Card Management | User Management
Community | Scoring | Integrated Services | 3rd Party Services

APIs are products. Developers are customers. Fidor APIs were designed with the developer in mind. That is why we adopted Internet standards set by global players like Uber, PayPal,  Facebook and Google.

Recent regulatory initiatives like PSD2 and the UK Open Banking Standard follow that route, too.

I.  Give your business customers easy and secure access to the banking infrastructure to automate their business processes via APIs

II. Integrate 3rd party services in your own offerings to enrich and deepen the relevance to retail and corporate customers via APIs

Fidor has a user friendly developer portal which supports all steps from learning with demo apps, app registration, sandbox, team management, approval process to app management, logging and debugging. End customer access is possible too. Enjoy testing against our APIs.

API Security

API security is provided at different levels: It starts with web security through an existing firewall, load balancing and business continuity technologies.

Access security is provided by risk managing static and dynamic scopes, configurations for Oauth 2, IP restrictions, access and refresh tokens, device management (in particular for mobile devices) and 2nd factor authentication services.

Operational security is supported by approval processes, rights and role models and backoffice solutions.

Additional security is provided through technologies against fraud, money laundery and other threats provided by 3rd party solutions that are connected to fidorOS.
