Stash Webhook to Jenkins triggers on branch create AND PR create

Question

We allow for branch create by pushing a branch. This triggers a build in Jenkins via the Stash Webhook to Jenkins plugin. This is not a bad as such...

But, when the user creates a PR for the pushed branch, a new build is started for the same branch. This is not a good thing since this consumes resources in our CI.

Is there something I have missed in config or is this simply the way it works?

Answering my own question since I got it to work the way I want. Which is that a build is ONLY started when a PR is created.

Config in Jenkins Git plugin:

Name:    origin

Refspec: +refs/pull-requests/*/from:refs/remotes/origin/pr/*

Branch specifier: pr/*

In "Stash Webhook to Jenkins" configuration

check the box for "Omit branch name".
