What I am most interested in is how to test/debug webhooks during development.

How do I tell webhook providers to send test notifications to my local development instance without tampering with the production setup on both sides?

This is another thing that Stripe nails. Out of the box it comes with a Test mode and you can easily use this to test your webhook implementation.

Another way to handle this is to create and maintain a mocking tool that will generate requests.
