Build API for mendix app

Hi Team, When I try to hit the build API via postman I am getting following error code. I have followed the this link Build API | Mendix Documentation which is provided by mendix. This is the following error response (attached Screen Shot) when I have tried with postman. The same issue has been replicating in free app and licensed app.   Kindly provide a solution on the below issue.   Thanks in advance.   This is the body of the content for this Post URL.

It looks like you have a GUID in the URL for AppID in your POST request, but the documentation says this should be the subdomain name of the app.

You can find the subdomain AppID to use for this by using the Deploy API.

Hope this helps.
