List Deliveries

List a destination's most recent delivery attempts (up to 50). Each entry is a delivery-provider attempt record. The attempt index lags actual delivery by a few seconds, and resolving a single message (get) / redeliver can lag longer (~30s+) — retry with backoff. See Webhooks.
path idstringrequired
Destination ID (whk_…).
data[].idstring
The message id — the key for get / redeliver; equals the svix-id header on the delivery.
data[].attemptIdstring
The id of this specific attempt.
data[].statusstring
One of success, pending, or failed.
data[].responseStatusCodeinteger
The consumer's HTTP response code, when the attempt reached it.
