What this gives your team

Connect payment activity to the systems you already run. Use the API to initiate and retrieve supported operations, then verify the server-side events that follow.

An explicit API contract

Use REST and OpenAPI documentation, decimal-string amounts and idempotency keys to make request handling predictable.

Webhooks you can verify

Verify HMAC-SHA256 signatures against the exact raw request bytes. Node.js, PHP and Python examples explain the signature and timestamp checks.

Delivery designed for retries

Handle repeated events safely. The delivery journal, retry history and permitted manual resend help you investigate notifications.
