OMNO API Documentation (2.2.0)

OMNO is a payment orchestration platform that processes Pay-In and Pay-Out transactions across multiple PSPs through a single API.

OMNO provides a single production environment. Testing is done in production using fake PSPs configured by OMNO; see the Testing in Production guide.

The final result of any transaction comes from webhooks or the GET transaction endpoints, never from redirects or client-side events.
