Introduction to OMNO Transaction API

Welcome to the SSEU Transaction API! This API is designed to provide a streamlined interface for managing online transactions, making creating, managing, and retrieving transaction information more accessible than ever. It includes a series of operations that handle everything from transaction creation to transaction status updates, refunds, and more.

Overview

OMNO Transaction API is a RESTful API designed to be easy to understand and integrate into any e-commerce or payment management platform. It was built to simplify complex payment processes and reduce the time needed to develop, test, and maintain payment-related functionalities in your application.

Purpose

This API is built for businesses and developers who need to interact with online payment systems. It helps you create and manage payment transactions, route transactions through various payment service providers, manage refunds, and export and import routing rules.

The OMNO Transaction API can be used by:

• E-commerce platforms: Simplify your checkout process by integrating OMNO's payment management features. With the API, you can process payments, manage refunds, and more, all from within your platform.

• Payment Service Providers (PSPs): Connect your PSP to the OMNO Transaction API to be part of the transaction routing rules, allowing businesses to choose your service as part of their transaction processing flow.

Using the API

To use the API, you must first authenticate your application. OMNO Transaction API uses OAuth 2.0 client credentials grant type for machine-to-machine authentication. After authentication, an access token will be returned, which can be used to authorize the API calls.

The API is organized around REST principles. It uses standard HTTP response codes and verbs and token-based authentication. All responses return JSON.

Our API documentation provides comprehensive information about each endpoint, including its purpose, the required input parameters, and the output. You can also find sample cURL commands to test the endpoints.

Getting Started

To get started, follow the instructions in our API documentation to authenticate your application and make your first API call. Remember always to protect your client's secret and never include it in client-side code or expose it in public repositories.

The OMNO Transaction API will provide your business with a seamless transaction processing experience. Happy coding!
