A live, self-provisioned sandbox of an at-least-once webhook delivery service.
No account needed. Everything below drives the real /v1 API --
the same one documented at /docs.
Issues a scoped API key, good for 60 minutes, capped at 3 endpoints / 20 events / 1 req/s.
One demo.triggered event fans out to
-- every endpoint subscribed to that type, which is what a webhook relay does.
There is no "send to just this one" API: subscribe destinations to different event
types if you want to target them separately.
-- Location:
Every delivery for this sandbox, newest first -- so # is the attempt number within its own delivery and the same numbers recur per destination. Rows marked deferred are not attempts: an open circuit breaker declined to send, so no request was made and no attempt was recorded.
| # | destination | status | latency | error | next retry | |
|---|---|---|---|---|---|---|
|
Paste the endpoint secret to verify a captured attempt, or tamper the body to watch it fail.

The HMAC was never compared. This is the replay-window check, not a bad signature -- raise the tolerance above s to check the signature itself.
