Using Bitbucket's HTTP request post receive webhook, I am able to notify Teamcity whenever there's commit made in any of the branch in Bitbucket. I have provided branch specification +:ref/heads/feature/* in TeamCity which is building the feature branch successfully on each commit made on the feature branch. However for our project, build on every commit is a bit of overhead and so we have planned to trigger the build automatically in TeamCity on creation of a pull request in Bitbucket. We have tried different branch specifications in Teamcity like +:ref/pull-requests/*/from, +:ref/pull-requests/*/merge, +:ref/pull/*/from and +:ref/pull/*/merge and +:ref/pull/*/head as specified on different websites but build is not getting triggered in Teamcity. I am wondering now if we really have a refspec to specify in TeamCity on pull request creation Bitbucket. Please assist
