I'm just wondering is clientId and clientSecret is same as appKey and appSecret. if so is any specific reason we have to set both. Thanks

https://github.com/ringcentral/ringcentral-php

return array(

'username' => '15xx53xx1', // your RingCentral account phone number

'extension' => '101', // or number

'password' => 'dsfXGfMdsfTdxsdfd',

'clientId' => 'sdfdst93w',

'clientSecret' => 'Vp7N7TwDsdfdsFbIuTaSINT84wNCWbODRQ',

'server' => 'https://platform.devtest.ringcentral.com', // for production - https://platform.ringcentral.com

'smsNumber' => '1800xxxx095', // any of SMS-enabled numbers on your RingCentral account

'mobileNumber' => '146xxx76', // your own mobile number to which script will send sms

'dateFrom' => '2018-07-10', // dateFrom

'dateTo' => '2018-07-12', // dateTo

'appKey' => 'sdfdst93w',

'appSecret' => 'Vp7N7TwDsdfdsFbIuTaSINT84wNCWbODRQ',

);

Those are not real
