Path parameters
id
The webhook endpoint's id.

The delivery's id.
Headers
Idempotency-Key
Idempotency token. Retries that reuse the key within 24h replay the original response. Up to 255 characters; a UUID is typical. See [Idempotency](https://docs.spreadspace.app/api/idempotency).
SpreadSpace-Version
Pin the API version, e.g. `2026-07-19`. Omit to get the latest. See [Versioning](https://docs.spreadspace.app/api/versioning).
Response headers
X-Request-ID
Correlation ID for this request. Quote it in support tickets.
Idempotency-Replay
Set to true when the response is replayed from the idempotency cache for a request that re-presented an Idempotency-Key it had already used. Absent on the original (winner) response. Replays are byte-for-byte identical to the original response body.
SpreadSpace-Version
The API surface version the server resolved for this request. Always present, regardless of whether the client supplied the request-side SpreadSpace-Version header. Default: 2026-07-19.
RateLimit-Limit
Request budget of the endpoint's rate-limit policy per 60-second sliding window. See [Rate limits](https://docs.spreadspace.app/api/rate-limits).
RateLimit-Remaining
Requests left in the current window. Suppressed on 429 responses produced outside the rate limiter (for example a usage throttle), where a remaining budget would be misleading.
RateLimit-Reset
Seconds until a guaranteed-fresh window.
RateLimit-Policy
The active policy in limit;w=window-seconds form.
