Hello,

Are you sure that you have correctly registered tokens provided by your client app ?
Have you tried to sent a notification with your token from the FCM console

[umairali]

Yes, I tried but I don't know why some tokens are not working and I received this message.

Same Issue here,

when I debug downstreamResponse I found this.
tokensWithError: array:1 [▼"<TOKEN>" => "InvalidParameters"

but when I try in postman with same parameters, it works

[rslhdyt]

It work's.

the problem is Firebase client for web (javascript), cannot receive notification with message payload
badge and sound. according to https://firebase.google.com/docs/cloud-messaging/http-server-ref.

working sample for notification to web.

$notificationBuilder = new PayloadNotificationBuilder();
$notificationBuilder->setTitle('title')
    ->setBody('body')
    ->setClickAction('http://localhost:8081');
$notification = $notificationBuilder->build();

Thank You @brozot for a Great Package

i have the same problem with same code (Sending a Downstream Message to Multiple Devices)
Laravel-FCM.INFO: notification send to 1 devices success: 0 failures: 1 number of modified token : 0
my client is android app, please help me to resolve this problem.

i can't see new message in firebase console.

[shinnlu]

i found the problem
when i get tokens from database with code:

$tokens = Subscribe::select('device_token') ->whereIn('UserID', $users) ->where('type','=','Alert') ->get();

it's return two dimension array like this:
Array ( [0] => Array ( [device_token] => TOKEN1 ) [1] => Array ( [device_token] => TOKEN2 ) )
it's wrong, the tokens array should be one dimension array like this:
Array ( [0] => TOKEN1 [1] => TOKEN2 )
