A webhook is a message a system sends to a URL you choose the moment something happens, such as a visual-assist session ending. It lets your work order or case update itself without polling.
Instead of asking a system every few minutes whether anything changed, your application registers a URL and the system calls it when an event occurs.
Service records stay current without integration code that polls. A session summary can land on the work order seconds after the technician hangs up.
ResolveGrid sends signed webhooks for session created, started, ended, and summary ready, each carrying your own reference ID so the event routes straight to the right record.
