Headers

Idempotency-Keystring

Optional client-supplied key for safely retrying mutations. Subsequent calls within 24 hours that share this key replay the original response — even if the request body differs slightly (a warning is logged). A retry that arrives while the original is still in flight gets a 409 request_in_progress. Keys must be 1–255 characters from [A-Za-z0-9_:.-]; a UUID is a safe default. Scope is per-endpoint and per-resource: the same key on a different route or path parameter is independent.

Request body

titlestring nullable

Display title for the job. Defaults to 'Filler Removal' if omitted.

callback_urlstring nullable

HTTPS URL to receive per-job webhook callbacks (filler_word_removal.success / filler_word_removal.fail). Delivery is best-effort with limited retries — poll GET /v3/filler-word-removals/{id} as the source of truth (a terminal GET may precede its webhook). Per-job callback_url deliveries are NOT HMAC-signed: authenticate them by verifying TLS and matching the echoed callback_id, and do not trust an unverified body. To receive a signed payload, register a webhook endpoint with a secret via /v3/webhooks/endpoints.

callback_idstring nullable

Opaque client identifier echoed verbatim in webhook payloads.

Response

Accepted — submission acknowledged; poll for completion.
