Firebase Cloud Messaging Sample

Demonstrates the Firebase push connector (FirebasePushConnector): sending push notifications through Firebase Cloud Messaging (FCM) to devices and topics.

What it shows

• Building a Message for push notification delivery to a device token or topic
• Sending via IMessagingClient using the firebase channel name
• Sending batch notifications to multiple targets
• Using dry-run mode for testing without actual delivery
• Validating messages against the Firebase channel schema before sending
• Retry policy with exponential backoff for transient provider errors (UNAVAILABLE, INTERNAL, DEADLINE_EXCEEDED)
• Viewing the channel schema, capabilities, and parameters
• Checking connector runtime status

Run

cd samples/firebase-push
./run.sh -- firebase <command>
