STET enables fast-track open banking API validation France

Helping banks and app developers to onboard effectively

Customer requirements

As part of PSD2, the European Banking Authority’s (EBA) Regulatory Technical Standards (RTS) requires banks offer a testing platform to financial application developers by March 2019.

STET decided to develop a standardized open-access API and companion testing platform to enable banks and fintechs to meet regulatory and legal requirements, ensure smooth integration between apps and bank infrastructure and expedite time to market for new services. To achieve this world-first initiative, STET needed:

  • A partner engrained in the financial services market that was familiar with test plan creation and the technical requirements of the RTS.
  • A partner who was well-established and flexible enough to deliver the test plan within a tight timeframe and in collaboration with a number of other players.
  • A test plan that can be easily integrated into a testing environment to meet evolving regulatory requirements and address the needs of markets across Europe.

FIME solution

Utilizing its expertise in the payments ecosystem, and over twenty years’ experience in financial services, FIME provided consultancy to help STET map the project requirements and highlight complexities and challenges. It provided a thorough end-to-end review of STET’s specification and offered recommendations for development of the testing platform.

FIME developed the test scripts in line with the specifications and compiled the application test plan. Working in collaboration with the sandbox supplier, these test scripts were then crafted into a software package and provided to participating banks and app developers.

The specifications and test platform have already been adopted by a number of banks in France and FIME continues to support the implementation of the open banking APIs.

Our mission to offer a standard open banking API and test platform was exciting but daunting, and FIME’s support has been central to making it happen.

We consulted a number of potential partners, but FIME’s testing knowledge and expertise in banking infrastructure really stood out.

FIME has enabled us to create a truly valuable and extensible service where users can access a single API and test platform in a secure, precise and controlled environment.

Driving the adoption of this standard in France and beyond is a priority for us now and we are happy to be taking this step forward in our strategy with FIME as our trusted testing and technical support partner.
