SIBS API Market provides in a single shared platform a dedicated interface to TPPs/PSPs including all PSD2 APIs (Payment Accounts Information, Availability of Funds and Payment Initiation).

You can browse on the available APIs, access functional and technical documentation and choose the APIs that best fits to your business needs.
Then register and immediately start testing it at our Sandbox environment, a portal designed for Developers that want to access the technical documentation (with code samples) and test the available APIs in a self-contained testing environment, with static data.

This solution is already available for testing.


SIBS API Market is a global and open API platform that aims to give easy access to a wide range of API for financial services.

Regarding the new paradigm of Open Banking, SIBS API Market was developed in order to connect banks with third party providers (TPP) to become connected, creating a vibrant ecosystem for the development of new services and business models, in context of the recent Payment Services Directive (PSD2) and beyond.
