This is the step most likely to get skipped by accident, because it’s easy to assume it’s only for apps sending push notifications. It isn’t – no build can be triggered at all without it.
Before you start
Your Package ID needs to already be set. This page is disabled with an “Action Required” message until Set your app’s name, slug, and package ID is done.
Steps
1. Go to Firebase Configuration
Open Settings → Firebase Configuration.
2. Upload three files
- Android Configuration – your Android config file from Firebase (google-services.json)
- iOS Configuration – your iOS config file from Firebase (GoogleService-Info.plist)
- Service Account Key – a separate service account key file from Firebase
3. Save, then check the connection
Save your changes, then click Check Connection to confirm.
Why this matters even if you’re not sending push notifications
Skipping this doesn’t just disable push notifications – it also blocks your ability to trigger a build at all. It’s one of the five requirements checked in What you need before your first build, independent of whether you ever plan to use push.
