I'm using the fcm_django package to send notifications API to Firebase but I have some confusion about those two concepts on Firebase like so: (registeration_id and device_id)
https://fcm-django.readthedocs.io/en/latest/#setup
I placed the "server_key" of Firebase to registration_id but don't understand what does device_id means and what is the value I should put on it?
after answering the above questions I tried to send notification from Django by the admin page on Django by creating registration_id which is "server_key" and defining the type which is a "web", but when I created this object I didn't see any message has been sent to Firebase cloud.
Note:-
I want to send notifications to only one device not many users.
so, can anyone help me to achieve this mission succeeded? Thanks in advance
