TL;DR is there a way to auto merge branches on Gitlab after review request on Upsource is approved?
The thing is, recently we decided to try Upsource with our team since Gitlab Community Edition doesn't provide more than one assignee for merge request. I set up an Upsource server, set up and configured our projects from Gitlab and so on and now we are trying to use it. But we found it quite disturbing that after you approve someone's review request you still have to go to Gitlab to merge branches manually. Could I use something like webhooks to merge branches after review request is approved?
