A customer requested 🔒 this:

A question for the Parabol team. We wanted to hook up the Github integration you have for Parabol to test them out.
Does your Github integration work with Github Enterprise? We have our own Enterprise instance, so we would want to have Parabol integrated with that one and not regular Github.
