The API client is divided into three sections:

The first part of the API client window consists of the following:

  1. A dropdown list of HTTP verbs
  2. The URL bar
  3. The Send button to dispatch your message to the endpoint(s) you created in the editor
  4. The Clear button to reset your API client window.
