By default Webhook To Jenkins for Bitbucket notifies Jenkins on all git reference changes, pull requests creations and re-openings. If users would like to limit which of these events trigger Jenkins, they can do the following.

Go to Advanced Configuration > Limit Events and select which events you'd like to disable. Each event thats disabled will be highlighted in red.

Here's an explanation of each event:

Pull Request MergedIs fired after a pull request is merged
Repository Refs ChangedIs fired when any sort of git reference change happens. This includes commits, pushes, edits, branch creations and more. Note, we filter out all reference deleted events.
