Firebase Notification not received on device when sent via cURL/PHP

I have an iOS app which is live on the app store. I am able to send push notifications to iOS devices which have the app installed, but only when I send them from the Firebase console.

When I try to send push notifications via a cURL request, the response from the server indicates that I was successful but the message isn't received on the device. I have tried this with both multicast and single recipient payloads.

I must be missing something more fundamental, but I can't see it.

Here is my PHP code:

// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'AI*****4LPGkx8xtDG2tBl*****7KWJfmp1szcA' );
$registrationIds = array( $_GET['id'] );
// prep the bundle
$msg = array
'message' => 'here is a message. message',
'title' => 'This is a title. title'
$fields = array
'to' => "cUxd-iTVVWo:APA*****kQTuqJ5RREKhhlJjm27NCuVfUn5APg3lBFqh-YWjgx*****iOpAQeLB14CzM2YTwIJo_75jzCmbFLKj0_zpKSHvAEbmJz*****BBezGJIng-N4H-cAD6ahY7mQNYZtEJLAIE",
'data' => $msg

$headers = array
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, '' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;

Here is the response I get when running this code:

There were two issues:

  1. I needed to include a notification section in the payload instead of data
  2. Somehow the payload wasn't being formatted properly by PHP.

In the end I used the PHP function shell_exec() to do a cURL request over SSH instead. This isn't ideal but it got the job done.

Example code:

shell_exec('curl -X POST --header "Authorization: key=<key here>" --header "Content-Type: application/json" -d "{\"to\":\"'.$to.'\",\"priority\":\"high\",\"notification\":{\"body\": \"'.stripslashes($message).'\"}}"');
