Interface strategy
The APIs are created according to the REST paradigm with respect to the architectural style HATEOAS. Because of the addressing logic shifted to the server, it is possible to extend the API organically without causing breaks for the callers.
If a modification cannot be implemented in a downward-compatible manner, previous versions of the interface are provided in parallel as required over a reasonable transition period.
The interface is always called via HTTPS encryption. We currently offer JSON as a data exchange format, but if required, an extension by further formats in the future is not excluded.
Structure of interface and documentation
The BANKS/Connect interface is divided into three sub-APIs: Auth API, Customer API, and Providers API.
Additionally, we offer AI/Connect for AI-powered financial data enrichment and PAY/Connect as an eCommerce checkout based payment solution.
For further information please refer to the comprehensive API documentation in the sidebar.
Central concepts like Authentication are described in the chapter of the same name. Furthermore, concepts applicable to each API are described in the respective API documentation.
