WebHook notification no longer works
Tags: webhooks
Oct 21, 2016 at 11:17pm   •   5 replies  •  0 likes

After successfully working for few days in the sandbox, my app stopped working.

My app uses PHP and cURL to call RC APIs and has both read presence and read account permissions. App uses OAuth 2.0 Authorization Code Flow.

It registers a webhook passing the following filter




and the following parameters

$post = array (

"eventFilters" => $filter,

"deliveryMode" => array(

"transportType" => "WebHook",

"address" => ""



I see my hook - subscription.php - being called first time during registration passing VALIDATION-TOKEN that is then returned back. The subscription returns success with a valid subscription id.

Here is a typical successful return from the registration API:

{ "uri" : ";,

"id" : "2ef8978e-82c1-4077-b335-03399984b47e",

"creationTime" : "2016-10-22T07:19:59.295Z",

"status" : "Active",

"eventFilters" : [ "/restapi/v1.0/account/144905004/extension/144905004/presence?detailedTelephonyState=true", "/restapi/v1.0/account/144905004/extension/144905004/presence/line/presence?detailedTelephonyState=true", "/restapi/v1.0/account/144905004/extension/146030004/presence?detailedTelephonyState=true", "/restapi/v1.0/account/144905004/extension/146030004/message-store", "/restapi/v1.0/account/144905004/extension/146031004/message-store", "/restapi/v1.0/account/144905004/extension/146032004/message-store", "/restapi/v1.0/account/144905004/extension/144905004/message-store", "/restapi/v1.0/account/144905004/extension/146032004/presence?detailedTelephonyState=true", "/restapi/v1.0/account/144905004/extension/146031004/presence?detailedTelephonyState=true" ],

"expirationTime" : "2016-10-29T07:19:59.295Z",

"expiresIn" : 604799,

"deliveryMode" : {

"transportType" : "WebHook",

"encryption" : false,

"address" : "";



When I test the subscription by calling the phone (RingCentral softphone is running) , the softphone pops up but the webhook is not called.

All direct calls to RC API work. I am able to get account info, extensions, etc.

It was working for few days. I am pulling my hair out!

How to debug this?

Any help would be greatly appreciated.

We run into the same problem today. We are in production for months. Today at 1.53PM presence hook no longer called. Our customers are affected. Need help.

I am experiencing exactly the same issue. I have a registered, active presence web-hook which stopped working on Friday. Push notifications still do not work in my sandbox as of Monday morning.

Hi Alec,

I have been able to verify webhooks for inbound SMS webhooks but not voice presence. We are investigating this now.

Please stay tuned.
