While using Curl or Invoke-RestMethod is quick and easy. Sometimes it is just easier to click Go and see the structured data right there.
For what it’s worth, you should be able to use the swagger docs themselves to test out API calls. However, this was never explored/explained/enabled by LM since the auth was too complicated for even swagger to decipher. However, now that bearer tokens are a thing, you should be able to put your bearer token into the swagger web page, provide the path and query variables for a call and run the call. That’s what the “Authorize” button is for at the top of the page (that they forgot to disable or couldn’t figure out how to disable). LM needs to turn on a couple flags when generating the swagger docs though (like the ability to specify the portal url, and the “execute” buttons that swagger normally offers), then it should be possible to run all the API calls you want right from the swagger docs.
