# Integration Testing

## Overview

The [MarketONE OpenAPIs](https://docs.saas.amdocs.com/bundle/MarketONEAPIs/page/index.html) can be tested to ensure seamless integration with the Merchant's back-end platform. While in test mode, the purchase or payment transaction should include a parameter on the API header `X-PLM-TEST-PAYMENT=true`. No additional parameters are needed as part of the payload while in test mode.

## Test Parameters

During live production calls, the test parameters should not be included. This facilitates real processing of payments and provisioning of service (as needed).
