@prashant-277 Did you do the android side? if so, did you try to kill the app, and attempt a call to the app? I'm struggling to receive call afterward. It only works the first launching time for me. I want to know is it a known issue for everyone

Hello,

This is Liubov from QuickBlox support.

The parameter device.client_identification_sequence is a unique hash to identify a client device in 3rd party services such as APNS or GCM/FCM.

Initially retrieved from a 3rd service and should be sent to QuickBlox to let it consequently send push notifications to the client.Here is the link to Server API for reference: Push Notifications (quickblox.com)

Please make sure that you pass client_identification_sequence in APNS format (not FCM or other) to create a push subscription for iOS.

Please follow this guide to configure push notifications and make sure that an APNS certificate and everything else is configured for your application.

Also, please review our Flutter documentation: https://docs.quickblox.com/docs/flutter-push-notifications#create-push-subscription

I am done this for get FCM token _firebaseMessaging.getToken().then((token) { setState(() { device_token = token; print("fcm token " + device_token); prefs.setString("fcmToken", device_token.toString()); }); });

then

Future createPushSubscription() async { try { List subscriptions = await QB.subscriptions.create(device_token, QBPushChannelNames.GCM); int length = subscriptions.length;

  if (length > 0) {
    _id = subscriptions[0].id;
  }
} on PlatformException catch (e) {
}

}

Hello @QB-nikolay-zolotarov ,

I still have the same issue when subscribing to Push notifications specifically.

I have the latest version: quickblox_sdk: 0.6.7-beta firebase_messaging: ^11.2.15 firebase_core: ^1.15.0

I followed the documentation to setup the project, and it is working fine for Android, but iOS devices show this error.

Can anything help me to resolve this? Thank you

Please make sure that you pass client_identification_sequence in APNS format (not FCM or other) to create a push subscription for iOS. To get a token, you need to use the User Notifications Framework. Please check how you get the token and let me know if you have any further questions. example: d07863267e7e511b533a22ff22a57ef0fb1e4518e14a8ea983c7143b76040e06
