Financial-grade gateway

Tyk’s financial-grade API gateway natively supports FAPI 2.0 (OAuth2 with DPoP proof-of-possession and PAR) and advanced OpenID Connect flows out of the box. Meet the strictest security and compliance benchmarks with OAuth2 authorization, token endpoints, enterprise OAuth clients, mTLS, and more.

Robust FAPI security

Tyk holds ISO 27001/9001 certifications and runs in PCI-compliant environments, providing a mature, audited API security foundation that complies with OBIE (UK Open Banking), PSD2 (EU), Financial Data Exchange (FDX), and other financial-grade profiles globally.

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 FAPIcompliant 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.
