In addition to pulling a perspective schema via the API, you can also view the schema of a Perspective through your browser. 

Paste the following URL into your browser and update the end of the URL with the ID of the Perspective:

https://apps.cloudhealthtech.com/v1/perspective_schemas/[perspective_id]

You can get the ID of a Perspective from the platform.  From the left menu, select Setup > Perspectives and click the Perspective that you want to view.  The ID of the Perspective appears in the browser URL.
