Export Historical user data from Firebase

I have setup a firebase project to track users events and for supporting push notification in my IOS and Android apps. In my apps I was registering for notifications when user completes sign up. However I have a number of users who just opened the app and didn't complete registration. I am planning to send notifications to such users to give them a nudge.

However I don't have the notification tokens for such users in my database. So is there any option to export the details of such users from firebase where I can grab their notification tokens?

I tried using big query and audiences but that wont work with historical data.

It sounds like you're using FCM tokens to send messages. In that case you will always needs an FCM token to send a message to a specific app/device.

FCM doesn't know anything about users of your app; all it knows about are the tokens.

So if you want to send a message to an app instance where the user didn't sign in, you'll need to store the token from the app in your database as soon as the app starts - even before the user signs in. Then when the user signs in, you can associate the token with their UID.

With those steps out of the way, you can query for database for tokens without an associated UID and send them a reminder to complete the registration.
