Google FCM Server: 200 but no notification sent to phone - ios

Question

I am working via Postman to send a FCM push notification to my phone that already has the app installed. I have push notifications enabled, the app is on the background, and I have a valid (confirmed) Firebase push token.
I'm POSTing to https://fcm.googleapis.com/fcm/send with the headers (Authorization: key=APP_SERVER_KEY, Content-Type: application/json), and my body looks like:
{ "notification": {
"title": "Portugal vs. Denmark",
"text": "5 to 1"
},
"to": MY_PUSH_TOKEN
}
I'm getting the following 200 OK response with body:
{
"multicast_id": MULTICAST_ID,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [{
"message_id": "0:MESSAGE_ID"
}]
}
everything looks fine, but I'm not getting a notification on my phone? How can I troubleshoot this, does anyone know what I'm missing?

Answer 1

Found the solution!
But before I offer the solution, here is a bit more background on the situation for others who might find themselves in a similar problem. I was able to POST and send a notification to an Android device, and I was able to send a push via the Firebase console to both Android and iOS device, so the only thing didn't work was sending the push to specifically an iOS device via a POST HTTP request (quite baffling).
I found this discussion here: https://github.com/firebase/quickstart-ios/issues/21. Basically for iOS, I was missing two othere parameters in the request body. I needed to set content_available to true, and priority to high.
so it looked like this:
{
"notification": {
"title": "Portugal vs. Denmark",
"body": "5 to 1"
},
"content_available": true,
"priority": "high",
"to": MY_PUSH_TOKEN
}
I believe the github discussion said something about how those added request body parameters allows FCM to push via APNS for iOS.

Thank you for your answer and explaining your context.
In my context, it wasnt working anyways.
So i added content_available and also replaced "text" with "body"
If anyone is still fighting with that, here it's how i handle it.
Cheers man !
import request from 'request'
const KEYS = require('../hardcodekeys')
export function send (title, message, ids) {
//POST: https://fcm.googleapis.com/fcm/send
//HEADER: Content-Type: application/json
//HEADER: Authorization: key=AIzaSy*******************
let push = {
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
},
content_available: true,
to: ids
priority: 'high'
}
let options = {
method: 'POST',
url: 'https://fcm.googleapis.com/fcm/send',
headers: {
'Content-Type': 'application/json',
'Authorization' : `key=${KEYS.FCM_KEY}`
},
body: JSON.stringify(push)
}
function callback(error, response, body) {
console.log(response.statusCode)
console.log(body)
console.log(error)
if (!error && response.statusCode == 200) {
var info = JSON.parse(body)
console.log(info)
}
}
request(options, callback)
}

Alternative working solution to send push notification to iOS device using php script.
Just change value for keys 'to' from fields array and Authorization from header array as per comment
//To Execute this this from Mac Terminal type php thisFilename.php
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'to' => 'fq5fI_wcXNY:APA91bGpR-qCYW01wNJ8pnp1ftfgR3DHqPk3ViXDqTYrq-p7MUhry9cPcpXEl7z4GFHGUPcTduww656Rks8cOpSZR-FjrseDX4S-eGdzGaBEqI46KWF8ZJmJpegbf3tzVZwILmnf64aU',//Replace with FIRInstanceID.instanceID().token() this you can get in Appdelegate, note this is NOT token received in didRegisterForRemoteNotificationsWithDeviceToken
'notification' => array (
"body" => "message",
"title" => "Title",
"icon" => "myicon"
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "AIdfdfzaSyC_0F8sqVqOgdg3Es4trWFcrNcrLpBjG6w06w",//This is Server Key, you can get it from Firebase console -> App Setting -> Cloud Messaging Tab - Legacy server 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_POSTFIELDS, $fields );
$result = curl_exec ( $ch );
curl_close ( $ch );
?>
