# Echo

## Overview

The Echo operation is used to test a request/response to a particular endpoint.
Note: This operation is not called directly but may be used in certain circumstances indirectly.

This operation, Echo (string), takes a single string parameter and echoes it back to the calling application. If the call is successful, the method returns the string parameter.
