Using Postman

Postman is a HTTP client for testing web services. This article explains how to make a call to the Codat API using Postman rather than the API Explorer.

If you don't have Postman installed, you can download it here.

Now complete the following steps in order. Don't worry, no coding is required!

Open Postman

Open up a new request in Postman. In the windows application, select the New button in the top left of the screen.

b. Add a new Header with the Key set to Authorization (note the US spelling) and Value equal to the Basic plus a space and then your Base 64 encoded API key from the previous step.

Your request should now look similar to below:


Execute your request

Select Send to execute your request.
