Newb dev here
There is a POST to the "client callback url" and my app receives a post request but I have no idea what I am supposed to send back in order to have it render a GUI for the user (when I send some plain JSON it shows up but HTML doesn't render as actual elements, just a bunch of text.)
Literally directions are:
- Box sends a request to the following URL (the primary callback URL plus the callback parameter):
http://www.doceditor.com/service?apikey=abc&file=&redirect=. - The response from the callback URL displays a user interface to the user who made the request. The popup has all the information needed to continue the action and an additional client callback is not needed.

How do I do that bolded part?
PS: If there is a good boilerplate please direct me to it!
