Same body, same event `id`, fresh timestamp and signatures. The attempt is logged with `trigger: manual` and never counts toward automatic disabling. Requires `webhooks:write`. Limit: 60 redeliveries per webhook per rolling hour. Events are redeliverable for 30 days; `webhook.test` deliveries cannot be redelivered (call the test endpoint again). ## OpenAPI ````yaml POST /v2/webhooks/{id}/deliveries/{delivery_id}/redeliver openapi: 3.1.0 info: title: Tavrn Platform API version: '2026-10-16' description: >- Enterprise API for medical record retrieval: cases, retrieval requests, retrieved records and provider invoices, case documents, and webhook notifications.

Scoped to your organization and kept for 24 hours. A retry with the same key and the same body replays the original status and body with `Idempotent-Replayed: true`; the same key with a different body returns `422 idempotency_key_reused_with_different_payload`; a retry while the first attempt is still running returns `409 idempotency_key_in_use`. Only 2xx and 4xx outcomes are stored - a 5xx releases the key so the retry executes again.
