Push Notification from Console not being delivered to client
I have added my Firebase Server Key correctly to Backendless Mobile Settings. I am also able to register my device via REST Api with the "deviceId" and "deviceToken" received from Firebase, which is my messaging service provider, as per the REST documentation similar to the below curl.
I notice the REST Api does not have a provision for sending the GCMSenderId similar to the native Backendless SDK device registration call below. Please confirm it's not required for REST Api.
I am however not able to publish from Backendless console to the device, the message simply does not get delivered. I am assuming Backendless requests Firebase, my service provider, to send the notification to the target user as identified by the deviceId/deviceToken, so my client is set up to receive the notification in the onMessageReceieved callback of Firebase's receiver, but nothing is received.
In any case is my Firebase server key enough for Backendless to know that i am using Firebase Cloud Messaging as my messaging service provider so as to direct the requests for delivery to the device there?
