Integration
Sentry
Confirms Sentry DSN delivery with a synthetic heartbeat.
An invalid or stale DSN means production errors vanish silently—you only discover observability gaps during your first real incident. PreFlight parses your DSN, sends a synthetic heartbeat event, and records provider response status so you know errors will reach the dashboard before launch day.
Requirements

"Sentry DSN from the production project your app reports to",
"Environment name (for example production or staging)",
"Optional Sentry auth token, organization slug, and project slug for extended API checks",

What PreFlight checks
| Probe | What it proves |
| --- | --- |
| DSN parsing | The DSN project ID and public key are valid and well-formed. |
| Synthetic heartbeat | A test event is accepted by Sentry ingest. |
| Provider response | Safe status and response metadata are recorded without logging secrets. |
| Environment tagging | Events arrive with the configured environment label. |
Failure guidance
| Symptom | Fix |
| --- | --- |
| DSN rejected | Copy the current DSN from the production Sentry project—not a deleted or rotated project. |
| Event not visible | Check Sentry → Issues after a successful probe; the heartbeat is intentionally visible. |
| Wrong project | Confirm the DSN matches the project your deployed SDK initializes with. |
| Rate limited | Wait and retry, or confirm you are not pointing multiple environments at one overloaded key. |
Dashboard setup
Navigate to Integrations → Sentry in your PreFlight project.
Paste the DSN from Sentry → Settings → Client Keys (DSN).
Set the environment name to match your production SDK configuration.
Run Pre-Flight Check and confirm the heartbeat appears in Sentry Issues.
