Developer Tool Guide
Push Notification test
Push Notification Testing Tool / Gateway Demo is designed to enable developers to test sending push notifications to Android and iOS devices. It appears as a simple interface where you can configure and send messages using both Firebase Cloud Messaging (FCM) and Apple Push Notification Service (APNs).

About Push Notification test
Push Notification test is designed for real development workflows where speed, clarity, and repeatable output matter. This page gives you a practical guide with setup steps, real-world use cases, validation tips, and troubleshooting playbooks so teams can use the tool confidently in daily work.
Key features
Upload the Firebase or APNs credentials you trust.
Compose a payload with headers, body, and target platform.
Rotate credentials and verify service account / APNs key scopes.
How it works
Upload Firebase service accounts or APNs certificates so the demo can authenticate directly without storing secrets.
Craft payloads, choose device tokens, and send pushes while watching live responses and error logs.
Who should use this
- Mobile engineers validating push payloads before release
- Support teams replaying incident payloads
- DevOps staff testing notification workflows for staging environments
Step-by-step usage
- Upload the Firebase or APNs credentials you trust.
- Compose a payload with headers, body, and target platform.
- Send and verify the delivery log before updating production rules.
Limitations / safety notes
Uploads stay in memory for your session; we never persist your certificates or service accounts beyond the current browser tab.
Real-world use cases
Release-day notification checks
Validate payload content, priority, and token targeting in staging before enabling production campaigns.
Post-incident replay
Replay failed push payloads from incident timelines to confirm whether failures are auth, token, or payload-structure related.
Cross-platform parity
Verify that Android (FCM) and iOS (APNs) receive equivalent notification content and metadata when campaigns go live.
Troubleshooting guide
401/403 push response
Likely cause: Expired credentials or missing role permissions
Recommended action: Rotate credentials and verify service account / APNs key scopes.
Delivered to Android but not iOS
Likely cause: APNs headers or topic configuration mismatch
Recommended action: Check APNs topic, push type, and certificate environment alignment.
Intermittent token failures
Likely cause: Stale device tokens after app reinstall or logout
Recommended action: Refresh tokens from client devices and prune invalid targets.
Implementation checklist
- Test payloads in staging before campaign launch.
- Log response IDs and error classes for incident replay.
- Separate credential sets for dev, staging, and production.
- Document rollback path for failed notification batches.

This guide is periodically reviewed so steps, troubleshooting, and recommendations stay aligned with current tool behavior and developer workflows.
Best practices before production use
Start with known-good sample data and save that baseline for your team. When behavior changes later, this baseline makes regression checks significantly faster.
Pair tool output with documented validation rules. The fastest way to avoid repeated incidents is to make output quality criteria visible in pull requests and release checklists.
Treat tool usage as part of your delivery workflow, not a one-time utility. Teams that standardize these steps get more consistent handoffs and less production debugging noise.
Tool-specific FAQ
Can I push to both Android and iOS from a single request?
Yes-the tool splits the payload and uses the right protocol (FCM for Android, APNs for iOS) while sharing your custom JSON body.
Is there rate limiting?
The demo enforces a soft limit to protect your credentials; if you hit it, retry after a few seconds or refresh the tool.
