I love being technical, it so fun. 1. it does not send a webhook - it sends data to a webhook from a workflow you have. (Those are two completely different things. It isnnot for custom feilds or values lol..... 2. You can make plenty of tools with that set-up EXCDEPT for calendar because it does not exist in workflows 3. The only ACTUALL way to do it is if you have a custom workflow built....... Using the right wording is important becuase other people read ths stuff.
