I have a multibranch pipeline setup with a Bitbucket server's repository with "Scan Multibranch Pipeline Triggers".

For that, a webhook is automatically created in Bitbucket.

Any push/pull request, branch builds are getting triggered also.

Now I want to preform extra steps if the event is a Pull Request.
For that, I'll need to read the Request Header/payload sent from Bitbucket.

Is there any way to read/print it in Jenkins build logs?

Multibranch -pipeline event logs:

I can see the payloads & X-Event-Key(Request header) are getting sent from autogenerated webhook, but cannot find a way to read it.
