Sentry issue alert webhook payload example

Sentry · event: event_alert (issue alert triggered) · content type: application/json

This is a representative sample — fake IDs, real structure. To see a payload with your data, point the provider at a capture URL (button below).

See it live, not frozen

One click creates a free capture bin with this exact payload already in it — pretty-printed, headers inspectable, replayable to your own endpoint:

Then paste the bin's URL into Sentry's webhook settings to capture a real delivery. No signup.

Things that bite people

This example's signature actually verifies: hex HMAC-SHA256 of the raw body with your integration's Client Secret — here the sample sentry_sample_client_secret_Kq8xT2v. Paste body + header into the signature debugger (generic scheme), or set the same secret on a capture bin (header sentry-hook-signature) for a live ✓/✗ badge.
The docs-snippet byte trap: Sentry's own verification example HMACs JSON.stringify(request.body) — a re-serialization of the parsed body. That only matches when your JSON serializer happens to reproduce Sentry's exact bytes; there's a long-standing report of event_alert deliveries failing the documented check (getsentry/sentry#31012). Verify against the raw body, and capture a real delivery to see exactly which bytes were signed.
Sentry expects a response within 1 second — the strictest deadline of any major provider. Respond first, process after; a capture bin answers instantly.
Switch on the Sentry-Hook-Resource header (here event_alert; also installation, issue, metric_alert, error, comment…) — for issue alerts action is always triggered and the rule label is in data.triggered_rule.
Sentry's docs literally recommend inspecting payloads with "an HTTP catch-all service" before you write your handler. That's the button below.

Send it yourself

Reproduce this delivery against any endpoint (your handler, a bin, staging):

$ curl -X POST https://your-endpoint.example/hook \
  -H 'content-type: application/json' \
  -H 'request-id: 2f9c1c5e-6d4a-4b8e-9f21-7c3a5d8e0b42' \
  -H 'sentry-hook-resource: event_alert' \
  -H 'sentry-hook-timestamp: 1787988600' \
  -H 'sentry-hook-signature: 948ba4569f58666a3aea977ee7270777a5c9041cab4b4afead92db955fdf91ce' \
