OMNO Transaction API

Welcome to the OMNO API documentation, your single source of truth for creating and managing Pay-In and Pay-Out transactions across multiple Payment Service Providers (PSPs).

OMNO is a next-generation payment orchestration platform that offers modular, scalable, and flexible integration tools for merchants and partners.

🚀 What This API Does

This API allows you to:

• Create Pay-In & Pay-Out transactions with multiple PSPs
• Generate hosted payment URLs for customers
• Automatically trigger webhooks for real-time status updates
• Retrieve transaction information using ID or Customer ID
• Integrate with OMNO’s internal services like Processing, Routing, PSP, and Webhook Services

The OpenAPI spec is defined in openapi_final_casefixed.yaml., and you can view it directly in the Docs tab above.

This API is designed to provide clean, fast integration without needing to directly connect with every PSP. OMNO handles the logic and routing behind the scenes.
