    );

    $headers = array(
        'Authorization: key='. API_KEY,

    curl_setopt($cn, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($cn, CURLOPT_POSTFIELDS, json_encode($fields));

  • First of all, you should check the registration token taken with trailing spaces removed is valid using Firebase console. If there isn't a problem with sending message to a specific device.

  • Then you should check the size of the field used to store the registration token in your database.In my case what happened I use phpMyAdmin, which uses MySQL/MariaDb database.And I have given length of 80 for varchar which caused truncating the registration token to the length of 80. So, it became invalid one. That is why I was getting 'InvalidRegistration' error. So I changed length to 200 which I think is enough. Wish this helps you.

InvalidRegistration-error is returned when a Registration ID (which you pass in via $registatoinids) is invalid, this error basically has nothing to do with your PHP-code or API-Key.

Just check out the registration id of the device you are trying to send the notification to and pass the (new) id when calling

'registration_ids' => $registatoinids

If your device does not have any reg-id, just re-register. Please refer to this section of the documentation.

Did u defined the vaule for API_KEY in your file.? See below php file. This is working for me.

<?php
    //Generic php function to send GCM push notification
   function sendMessageThroughGCM($registatoin_ids, $message) {
        //Google cloud messaging GCM-API url
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
            'registration_ids' => $registatoin_ids,
            'data' => $message,
        );
        // Update your Google Cloud Messaging API Key
        define("GOOGLE_API_KEY", "API_SERVER_KEY");         
        $headers = array(
            'Authorization: key=' . GOOGLE_API_KEY,
            'Content-Type: application/json'
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);   
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
        $result = curl_exec($ch);               
        if ($result === FALSE) {
            die('Curl failed: ' . curl_error($ch));
        }
        curl_close($ch);
        echo $result;
    }
?>

Define your API_SERVER_KEY in this line.

define("GOOGLE_API_KEY", "API_SERVER_KEY");

"InvalidRegistration" means Registration id that you sent is not registered. Check API key and registration id correctly.
