POST `/api/v1/webhooks/{id}/deliveries/{deliveryId}/redeliver`

Send a delivery again.

Scope webhooks:write
Idempotency-Key
operationId webhooksRedeliver

The token needs the scope webhooks:write, and the person or service account behind it needs the matching privileges and account permissions, exactly as on the screens. See Scopes.

Idempotency-Key. Send a unique Idempotency-Key (up to 255 characters, e.g. a UUID) with every POST. Retrying with the same key and body replays the first answer for 24 hours, so a timeout never creates a second order; the same key with a different body is refused (idempotency_key_reused).

Status codes and errors

Errors are application/problem+json (RFC 9457) with a stable code to program against; the detail says what to fix. See Errors.

Status	When	Problem codes
200	Success
200 / 201	The same Idempotency-Key again: the first answer is replayed (24 hours)
400	The request is malformed	`invalid_request`
401	No token, or it is invalid or expired	`invalid_token`
403	The token lacks the scope, or the person or service account behind it lacks the privilege or account permission	`insufficient_scope` `forbidden` `ip_not_allowed`
404	Not found, or not visible to you (the API never confirms what you may not see)	`not_found`
409	Not possible in the current state	`invalid_transition` `conflict` `idempotency_in_progress`
422	Validation failed (the detail says which field), or blocked	`validation_failed` `idempotency_key_reused`
428	A required header is missing	`idempotency_key_required`
429	Rate limited: wait for Retry-After seconds	`rate_limited`
