I am getting this "WebHook is not reachable" error. I hit index.php from cmd at that time its showing this msg. Even I catch one more error "Invalid request (Unexpected EOF)"
Because of what i am getting this error?
The webhook URL service must meet the following requirements:
Validation-Tokenheader on subscription
TLS / SSL only needs to be enabled in production. For development purposes, TLS is not necessary.
For development purposes, you can use localhost along with a service like ngrok.
I found the references and clues here in this link - http://ringcentral-api-docs.readthedocs.io/en/latest/webhooks/
