# Omni-Channel Payment API

A single set of REST endpoints for taking payments in person, online, and by bank transfer across the United States and Canada.

The Integrated Commerce Omni-Channel Payment API is a RESTful API that provides a unified interface for processing payments across multiple channels. It lets you integrate payment processing into your applications with a single set of endpoints, simplifying implementation and reducing development time.

The API supports integration in both the United States and Canada, using USD and CAD currencies.
