TestFCM.in is a free tool for testing Firebase Cloud Messaging HTTP v1 push notifications. We welcome reports about send errors, UI issues, documentation gaps, and feature suggestions.
When contacting us about a failed notification, include your error message (without sharing production secrets), platform (Android/iOS/web), and whether you used a fresh OAuth token from gcloud auth print-access-token.
We typically respond within a few business days. Thank you for helping improve TestFCM.
