Using a sandbox app, PHP SDK. Trying to create a subscription, with the payload
Array ( [eventFilters] => Array ( [0] => /restapi/v1.0/account/~/telephony/sessions ) [deliveryMode] => Array ( [transportType] => WebHook [address] => https://64979567.ngrok.io/index.php?m=integrations/webhooks&a=ringCentral ) [expiresIn] => 630720000 )
This is what gets posted to my webhook address,
POST /index.php?m=integrations/webhooks&a=ringCentral HTTP/1.1 Validation-Token:
d206fc96-ef23-4fe9-98c2-a087358446c7
Content-Type: application/json; charset=UTF-8 Accept: application/json Accept-Encoding: UTF-8 User-Agent: RingCentral-WebHook/8.3 Content-Length: 0 Host: 64979567.ngrok.io X-Forwarded-Proto: https X-Forwarded-For: 192.209.29.132
This is what my webhook returns,
HTTP/1.1 200 OK Cache-Control: no-store, no-cache, must-revalidate

And what I get back from the API is "WebHook server response is invalid". I'm not sure what's missing, here.
