We can already specify a URL to hit via Magic Agents to leverage automation capabilities of other solutions such as Rewst. We could improve the security of these operations by allowing for the creation of security header names and values. This would allow webhook listeners to reject requests with a 4XX http status that don't have the appropriate value instead of accepting all requests and discarding malformed message bodies. In the current scenario, every request would result in a success code. This could lead to potential abuse by threat actors.
