Hi Support

I'm using javascript SDK for send SMS feature and app is under development mode. I'm getting 400 bad request when I post request for Send SMS. Here is my code

function send_sms($phone,$message){        

          $json_data = {            

                    "from": {

                            "phoneNumber": "+1000000000"

                    },

                    "to": [{

                            "phoneNumber": $phone

                    }],

                    "text": $message    };

          platform.post('/account/~/extension/~/sms',$json_data

          ).then(function(response) {

              console.log(response.json()); 

              //alert('Success: ' + response.json().id);

          })

          .catch(function(e) {

              //alert('Error: ' + e.message);

          }); 

    }

Please let me know how to resolve this issue??

Thank you!
