Raw HTTP is actually perfect for me! Thank you!

To be clear though, I still haven't figured out how to actually put in a POST body. It's fine to use URL params for something like differential.querydiffs, but I can imagine the problems I'll run into with URL length when doing harbormaster.sendmessage (especially when reporting a bunch of unit test and linting results).

OH, that only happens if you do the human-readable option. I didn't notice that little box at the bottom had changed amidst the giant blob of json that the call returned.

The good news though is with that hint I seem to have it working without even needing to POST: https://phabricator.myurl.com/api/differential.querydiffs?api.token=api-TOKEN&ids[0]=5

I can definitely try either of those two options, but to my point, it wasn't obvious to me from the documentation:

Where does this feature stand? I wasn't able to find any documentation on how to use this, but it also looks that a non-trivial amount of work has been completed towards this goal. Is this something still in the immediate roadmap? Being able to easily integrate GitHub issues into Phabricator (and back) is a big roadblock to adoption for us.
