Can I use webhook action with a non-HTTPS URL?
We do not allow users to configure webhooks with non-HTTPS URLs as those are inherently unsafe. HTTPS has become standard on the web with special thanks to Let’s Encrypt, which offers free SSL certificates and automated integrations with many web hosting providers. It should be free and relatively easy to enable an SSL certificate for your domain.
To test a rule on a local server running on your computer, you could use a service like Ngrok to create an HTTPS tunnel.
