How to register a custom webhook

I have encountered a use case where we will be using SolarWinds to facilitate user registration for our platform. For a certain type of high-value user, an internal team member will submit a solarwinds service desk ticket with all the information needed to register the user. I'd like to register a webhook so that when a ticket of that type is submitted, it automatically POSTS the ticket information to the endpoint I've registered. Or sends a signal of some kind to let the service know to poll for the registration details. 

Please let me know if this is something you support natively, and if not how you would recommend addressing this use case.
