We've launched a limited public beta of a new feature in the GitHub CLI: webhook forwarding.
All it takes to start receiving webhooks locally is one simple command:
gh webhook forward --repo monalisa/hello-world --events issues,pull_request --url http://localhost:4000/webhooks
With webhook forwarding, you can iterate quickly on your integration without having to deploy your code to a test environment.
To request access to the beta program, post in our GitHub Community discussion. We add new beta users on a regular basis. Once you've been added, you will receive an email at the address registered on your GitHub account.
For more details on this new feature, head over to the docs – see "Receiving webhooks with the GitHub CLI".
