Here are the links to the REST APIs dependent on your application. Click the link appropriate to your requirements.

Once you have the list of APIs displayed, you can click on the Endpoint you are interested in to get more information.

For Example: Offices:
In your software, you send: GET /offices

You get the response: HTTP/1.1 200 OK ... this tells you that you should get the HTTP response code that everything is OK. The response that is returned by the Offices endpoint is displayed. This allows you to check that the response you are getting is correct. For the expected response, see the image below.
