Unique list of Requests types that are tied to a single issuetype from JSM

Question

I would like to pull a list of unique request types that are associated with a specific issuetype, and display the Request Types. Basically create a list of all the Unique Requests types in a confluence page to document the available options.

Example: 
Standard Change (issuetype)

Change A
  Change B

etc..

I have read through a couple posts that make it seem like it is possible, but haven't found a good approach. The one approach I found didn't seem to work.

You should be able to do this using the REST API by getting the issue types that the project has by using the Get issue types for project endpoint and then get the request types using the Get all request types endpoint. The latter one will have the ID of the issue type it is associated with and you can then cross reference that with the output from the first end point.
