Send Webhook Endpoint Test Event
Fluveo extension (Test mode only): send one signed synthetic test event of type to this endpoint’s saved URL and answer what the endpoint returned. The event is marked in its signed body (livemode: false, fluveo_test_event: true, an evt_test_ id), is never listed in /v1/events, and is never retried. Disabled endpoints receive test events and stay disabled. Only saved URLs using https on port 443 can receive a test event. An optional Idempotency-Key header sets the test event id: the same key, endpoint, and event type always give the same evt_test_ id, and there is no replay journal. A malformed key (more than one header, empty, non-printable, or longer than 255 characters) is refused with 400. Any query parameter is refused with 400. Test events are off unless enabled for the environment; when off, the send is refused with 400 webhook_test_events_disabled. Limits, each a sustained rate with a burst of the same size: per store and mode sustained 20 per minute with bursts of 20; per endpoint sustained 5 per minute with bursts of 5; per destination host, store, and mode sustained 10 per minute with bursts of 10; per destination host across all stores sustained 300 per minute with bursts of 300.
Authentication
Standard Basic HTTP authentication. The username is the Fluveo secret key and the password must be empty, encoded as base64(api_key:).
Bearer HTTP authentication. Allowed header: Authorization: Bearer <api_key>.
Path parameters
Request
One of the 18 Stripe event types Fluveo delivers; platform hs.* types are refused
Response
Fluveo extension response: the outcome of the one test delivery (a failed delivery is still a 200)
Milliseconds from the request to the response headers; null when no request was made
At most the first 1024 bytes of the endpoint's answer, as text: control characters become spaces and every webhook signing secret with its prefix (any letter case) is redacted. Returned once and never stored; null when no body was read, including routers built with the local webhook allowlist.
