You can use [Postman - a free Google Chrome Extension](https://chrome.google.com/webstore/detail/postman/fhbjgbiflinjbdggehcddcbncdddomop?hl=en) - to make an outgoing call using our [Call APIs](https://developer.exotel.com/api/#call-agent), and the steps to do so are as follows:

::embed[**Step 1** - Add Postman as an Add-on for your Google Chrome browser. This [video tutorial](https://www.youtube.com/watch?v=8veXJ9YGlFI) should be useful.]{url="https://www.youtube.com/watch?v=8veXJ9YGlFI"}

If the plugin is not working, you can use this function directly by downloading the free Postman App.

**Step 2** - Sign up and begin importing this [collection configuration](https://www.getpostman.com/collections/c91ac4d856b51ece287b) after launching the app (by clicking on [https://www.getpostman.com/collections/da36b086217bca1fb732](https://www.getpostman.com/collections/da36b086217bca1fb732), the collection's settings will be automatically imported to your Postman app/account).
