How to get started with outgoing Asana webhooks

I am struggling to figure out how to create outgoing webhooks from Asana. I’ve never created a webhook before and struggling to find basic information I need to start learning.

I have seen the documentation at Establish a webhook - this assumes more prior knowledge than I have, and searches here give results about specific problems.

For the immediate task, I need to set up an outgoing webhook that is triggered when a task is created/assigned to me. Is there a web interface I can use to set this up? If not, then what tools do I need in order to set it up? What documentation should I be reading? Is there a good primer on webhooks you can recommend?

Any help you can give me on starting my learning journey on webhooks would be most appreciated.

Hey, did you get some outgoing webhooks working?
