Hi Hassan,

If you are using custom SSL Certificates you could adopt the following methods to set the path to the PEM file :

1.) Within the SDK

This option would require modifying the SDK the  Cient.php code. When using this approach, ideally the path parameter could be passed into the SDK.

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);  curl_setopt($ch, CURLOPT_CAINFO, "/path/to/cacert.pem");    

 2.)  using the php.ini file
You would have to add this to the php.ini file :
curl.cainfo=/path/to/cacert.pem 
For more detailed information Refer to this in our Github-PHP-SDK-Issue

Could you verify if the certificate is valid if you are using the option 2 specified above

Hi Hassan,

The reason you are getting that error is because your application is of type "Public" and we make sure that all the RingCentral Applications of type Public implement the  Authorization Code Flow mandatorily.

Kindly take a look at our demo in PHP here :
https://github.com/grokify/ringcentral-demos-oauth/tree/master/php

For further information on Authorization Flow, please refer to our documentation here :
https://developer.ringcentral.com/api-docs/latest/index.html#!#AuthorizationCodeFlow

Let us know if you are able to get it working. Thanks.

If you're using an OAuth 2.0 request using the OAuth 2.0 you need to provide the correct grant_type while making a call

Please note, application created with different platform type will have different grant_type.

If your application is public then most of the case the grant_type will be Authorization code where you need to login using your user ID and password. It will be launching a browser window to make a call to an authorization URL implementing a 3-legged (Authorization Flow) auth in you PHP code. Also for the issue you are facing, you also need to check the SSL certificate you are using.

RingCentral JavaScript SDK has methods to handle the authorization code grant flows.
