Hook on pull request creation

The question:

Is it possible to create an arbitrary action that executes when a pull request gets created?

The use case:

I would like to create a Jenkins job, based on a standard set of rules, each time a pull request is created in a Stash repository.  I can use Jenkins polling to watch the branch from there and keep building on commits.  Also, I can use a merge request check plugin to approve or deny the merge based on the Jenkins build status.  Finally, I can clean up leftover jobs from merged pull requests using some yet-to-be-determined process.

The easiest way to implement this would probably be to write a third service that uses APIs of both applications to handle this asynchronously (with the notable exception of the merge request check).  I would like to avoid creating a separate entity, and so I am left with the question above.

If I'm barking up the wrong tree and someone has a suggestion for a better implementation, I'm all ears.  I'm still in the early stages here and haven't committed to any particular method.

You need to write a plugin that listens to the PullRequestOpenedEvent. For the Jenkins part, you can use the Jenkins webhook for inspiration.

Thanks for the quick response! Is there a concise list of events that can be listened for that I missed somewhere in the documentation?
