Welcome to the RingCentral Community

Hello everyone,

I'm using PHP REST API to send SMS, but unable to send SMS. My request is successful and return SMS ID with all the details but the SMS status is 'SendingFailed', I don't know why?

There is nor error code returned in the response. Please help me to get the errors that why the SMS not sent.

My request code is as follows:

$url = "https://platform.devtest.ringcentral.com/restapi/v1.0/account/~/extension/~/sms";
$param=json_encode(array('to'=>array(array('phoneNumber'=>$to)),'from'=>array('phoneNumber'=>'+19164374306'),'text'=>$smsBody));
$response = http($url,'POST',$param,$auth_token);

The response I'm getting is :
