Before making any REST API calls, your account needs to be authenticated. For this example, we will demonstrate our API calls using Postman, however this would be coded programmatically in whichever language your website or service is coded in, such as: PHP, JAVA, c#.NET, etc. Before beginning the authentication process, be sure your IP address has been whitelisted. 

1. Open the Postman application, or the REST application of your choice.
2. Open https://api.dev.listrak.com/sms in a browser window.
3. In the browser window, navigate to the Authentication Tab on the left-hand side.

4. Copy the Token Endpoint URL (https://auth.listrak.com/OAuth2/Token).

5. Navigate to the Postman app.
6. Paste the copied URL into the Enter Request URL box.

7. Select Post from the drop-down menu.
8. Click Save to update and save the Authentication request for later use.
