Replay

Replay re-sends a captured webhook to any target URL. The killer use case: a customer reports a bug, you grab the exact failing payload from production, and replay it locally as many times as you need until your handler stops crashing — without waiting for the real provider to send another event.

How It Works

1. Open the request you want to replay in the inspector
2. Click Replay in the request detail panel
3. Confirm or edit the target URL, method, headers, and body
4. HookSense sends the request from its servers and shows you the response status, body, and latency

SSRF protection is active on all replays — internal IP ranges (RFC 1918, link-local, loopback, metadata services) are blocked. To target localhost, use the CLI instead, which forwards to your machine over the existing HookSense connection.

Edit Before Sending

Replay opens an editor pre-filled with the captured request. Tweak any field before firing:

• Target URL — your local server, staging, or a different production endpoint
• HTTP method — switch GET → POST or any verb
• Headers — add, remove, or rename keys (handy for impersonating different content types or auth)
• Body — JSON, form-encoded, or raw text; the editor preserves whitespace

Edits don't modify the original captured request — replay is non-destructive.

Repeat Mode

Need to load-test or check idempotency? Toggle Repeat in the replay dialog:

• Up to 50 repetitions per replay
• Configurable delay between sends (0–10s)
• Per-iteration response status, body, and latency
• Stop early at any time

Use cases: testing your handler's idempotency key, simulating duplicate-delivery scenarios, warming up caches before a load run.

Replay From the API

curl -X POST https://hooksense.com/api/endpoints/YOUR_SLUG/replay/REQUEST_ID \
  -H "Content-Type: application/json" \
  --cookie "hs_session=..." \
  -d '{"targetUrl":"https://staging.example.com/webhooks","method":"POST"}'

See the API reference for full request/response schema.

Replay History

Every replay (one-shot or repeat-mode) is logged on the request's detail panel: target URL, response status, latency, and timestamp. The 10 most recent target URLs are remembered locally for autocomplete.
