I send a message with information only for the message fcm.googleapis.com/fcm/send and get its ID:
{"message_id":6399566057759755347}
After that, I can’t find this message in the notification list of the firebase console, but I need to get data on the number of receivers and opening notifications and display them on my service (I need to get conversion data by API). Is there any way to implement it? If not, is registering delivery and opening notifications on my own server, is this a good idea?
