Webhook Setup Error: Invalid resource owner credentials

Bhagyashree,

When you are subscribing to Webhooks using the UI in the developer portal ( App -> Webhooks ) the Webhook URL must respond with the Validation-Token immediately. Please read below.


Enable Webhooks using UI:

When you enable Webhooks using the UI as shown below, your app need not Create a Subscription via Webhook instead respond immediately with a HTTP 200 and a Validation-Token in the header.



The Glip-Botman code that you are referring to is creating subscription inside the application, instead please make sure that when you 'Verify' the Webhook URL would have the below code:

<?php $callbackBody = file_get_contents('php://input');
$callbackSignature = getallheaders()['Validation-Token']; 
header('Validation-Token: '. $callbackSignature); http_response_code(200);   

Invalid resource owner credentials :

You do not have to provide User Credentials when you are creating the Webhooks using UI. As shown above, your webhook URL would need to respond with a HTTP 200 and the Validation-Token. 

If you are creating an application of Type == Server/Bot, then I recommend you go through this tutorial for more information:
http://ringcentral-api-docs.readthedocs.io/en/latest/glip_bots/

If you are using the Glip-Botman library please use the branch 'Bot-provisioner'
