PayFanoutOne payment API. Many PSPs.

A unified, stateless multi-PSP abstraction for React + TypeScript. Adapt any payment gateway behind one API and one set of embedded UI components, add the next PSP by writing an adapter, with zero changes to your application code.

API reference

One API over every PSP

Application code never knows which PSP is active. Add any PSP by writing a new adapter package only, zero changes to core, zero changes to your app.

Stateless by design

No database, persists nothing. PayFanout orchestrates and normalizes; your app owns id mapping, webhook dedupe, and audit logs.

We never store card data

Card capture lives only in the PSP's hosted, embedded card fields (SAQ-A eligible). No raw card input anywhere, saved cards are opaque PSP tokens.

Embedded, not redirected

Fields render inside your UI, styled by your design tokens; 3DS/SCA runs inline. Genuinely redirect methods (iDEAL, PaysafeCard…) are modeled honestly via a flow capability.

Failover & circuit breaking

PaymentRouter cascades transient failures across PSPs per currency/country, with a circuit breaker that skips known-down providers, the attempts array is your audit trail.

Proven extensible

A shared conformance suite runs the identical contract against every adapter. A future adapter is done when it passes the same tests every shipped adapter passes.
