Postman is a powerful HTTP client for testing web services. It is available as a Google Chrome Application (Extension ) as well as a desktop application. All API calls sent using the Postman app are stored in history (the calls are displayed in the left sidebar). This allows you to use them at any later point of time. AutomationEdge (AE) is a REST based web application. Postman can used to call or test the REST APIs of AutomationEdge. For more information regarding how to use Postman for making REST calls to AE, please refer to the following: > [@AE Rest APIs](https://community.automationedge.com/t/ae-rest-apis/189/3): > > Postman is a powerful HTTP client for testing web services.
