Hello, I have a question/request - I have made callback/webhook stub in WM and it works but I am currently stuck on how to access needed data from original request header. I need to pass an id from original request header to callback but I have no idea why. In WM documentation I have found only examples of how to pass parts of request body using jsonpath. But as far as I know request header is not JSON so it cant be used. Can any1 help? Crosspost from #general
