How to Check Your Firebase and Google Analytics Connection

Updated 2026-09-043 min read

Short answer

Open Project settings then Integrations in the Firebase console. An enabled Google Analytics integration names the GA4 property it feeds. If no property is named, the link is not finished.

People often assume Firebase Analytics and Google Analytics are the same product wearing two badges. They are closely joined, but the join is a configuration step somebody has to complete, and a project can sit for months collecting nothing because it was skipped.

What the link actually does

Your app talks to Firebase. Firebase forwards analytics data into a GA4 property. Reporting — realtime, retention, funnels, everything you eventually read — happens on the GA4 side. Without the link there is a collector with nowhere to deliver.

The chain, in order
App with the Firebase Analytics SDK
→ Firebase project
→ linked GA4 property
→ GA4 reports
→ tools that read GA4, such as Appnaly

Checking the link

  1. Open the Firebase console

    Select the project your app is configured against — not a similarly named one.

  2. Go to Project settings

    The gear icon beside the project name in the sidebar.

  3. Open the Integrations tab

    Find the Google Analytics card.

  4. Read what it says

    Enabled and linked shows the GA4 property name. Not enabled means analytics data has nowhere to go, and you can enable it from there.

Note: Write down the property name you find. Most "my data is missing" cases end with someone discovering they were reading a different property from the one their app feeds.

Confirming from the GA4 side

The check is worth doing in both directions, because the two consoles describe the same relationship in different words.

  • In Google Analytics, open Admin for the property named in Firebase
  • Look at the data streams — your app should appear as a stream, with its bundle ID or package name
  • Confirm the identifier matches the app you actually ship, not an older or test identifier

Things that break the link without looking broken

SituationWhat you see
Analytics never enabled on the projectNo property named in Integrations
App registered under a different Firebase projectLink looks fine, but your app is not in it
Config file from another project in the buildEvents go somewhere you are not watching
Bundle ID or package name mismatchData stream exists but receives nothing

Careful: Enabling Analytics does not backfill history. Collection begins when the link starts working, and the days before it stay empty permanently.

How this affects Appnaly

Appnaly connects to Google Analytics, not to Firebase. It lists the GA4 properties your Google account can read and builds your app list from the data streams inside them. A Firebase project with no linked property is therefore invisible to Appnaly — not because of a permission problem, but because there is no GA4 property for it to find.

If your app is missing from Appnaly, checking this link is usually a faster answer than re-checking permissions, because it fails in a way that looks identical from the outside.
