Take a look at Cloud Functions. They will do exactly what you need for this.

There's a few pieces you'll need to setup and understand about firebase, so checking out a basic tutorial on that first would be a good plan too.

I did a session recently where we built an application on stage, and the Cloud Function that brought our device telemetry over into Firestore (not Firebase RTD, but same concepts in an updated package):

That's the code for the Cloud Function itself. To understand the concepts around the pieces you're looking at, check out:

https://firebase.google.com/docs/ <-- getting started guides for Firebase (although again, I'd recommend going straight to Firestore)

and
