Web push notification error with curl send message

Question

I want to understand what is web-push and how can i use for my projects... Have found this example https://mobiforge.com/design-development/web-push-notifications But always getting an error when try to send notification via Firebase Cloud Messaging (FCM is the new version of GCM)

{"multicast_id":6440031216763605980,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

What it means "InvalidRegistration"? What i'm doing wrong?

My php curl, but i am sure that there is no problem here

$link = "https://gcm-http.googleapis.com/gcm/send";

$header = array();
// $header[] = "Content-length: 0";
$header[] = "Content-type: application/json";
$header[] = "Authorization: key=AIzaSy...";

$contentArray = array(
    "collapse_key" => "All",
    "registration_ids" => array(
        "gAAAAABX06BLKhA4n1yHNlsyzu02wxsDjZf89oxIljwM4ZdLpMZU7ty64TFEYahPQZaTmCeYlJo-WDWnfFHOKXzKURhNtRWmN0OgBgn9hJdmgatSGoiTkt69TeJpiD8F034WOr5HMEG2",
    ),
    "data" => array(
        "title" => "This is a Title",
        "message" => "This is a GCM Topic Message!"
    )
);
$jsonData = json_encode($contentArray);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $link);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
$string = curl_exec($ch);
echo $string;

$data['curl'] = curl_errno($ch);

if(!curl_errno($ch) && !strpos($string, "503"))
    $data = array_merge($data, explode("\n", $string));

curl_close($ch);

You're using FCM, but with the old GCM protocol, I'm not sure that's supported. I'd suggest you to use github.com/web-push-libs/web-push-php, so you don't need to implement it yourself. — Marco Castelluccio

Please try checking the subscription ID that you used.

As mentioned in Check the response,

If the response shows an invalid registration error, check the subscription ID you used.

As discussed further in making a request to GCM, make sure to use your own API key and subscription ID when you run the cURL command.

For more information, please check the documentation on how to send a request from the command line for GCM to push a message.
