Redmine

I would like to integrate BPMN into our Redmine Install so each ticket can be assigned a process that is followed.

I'm looking for the best option to do a webhook from Redmine to pass data on to the Process?

What would be the best option?

I've looked and I think the Webhooks Plugins have all stopped be actively supported so I'm wondering if a custom Plugin would be hard.

Any ideas would be greatly apprecisated.
