Faster development
Jumpstart your Open Finance project with Tyk’s prebuilt Mock Bank and TPP Sandbox. Validate OAuth flows and test consent handling, conformance and API integrations immediately, without waiting for a live bank or building fake endpoints. Focus on business logic, not plumbing.
Accelerate time-to-market with the Tyk FAPI repository
The Tyk FAPI repository serves as a turnkey “accelerator” for financial-grade APIs. It includes a gRPC plugin for DPoP (proof-of-possession) authentication and configurations for FAPI‐compliant OAuth servers. It directly addresses stringent OBIE and PSD2 security requirements with advanced OAuth2 profiles (FAPI 1.0/2.0, DPoP, PAR) out of the box.
Tyk’s full-stack reference implementation greatly accelerates time-to-market for compliant banking APIs. It provides client SDKs (Java, Python, Node) and prebuilt components (mock bank, TPP app, test tools) so you can code without building from scratch.
