Pass a callback_url when calling generate_clips to receive a POST when all clips are ready.
Completed:
Failed:
Clips are sorted by score (highest first). We retry up to 3 times if your server doesn't respond.
Signature verification (optional): Each callback includes an X-Crabcut-Signature header. Compute HMAC-SHA256 of the request body using SHA-256(your_api_key) as the signing key. Compare with the header value (sha256=<hex>).
Using with n8n
Option A — Webhook (recommended):
- Create a workflow with a Webhook trigger node. Copy its URL.
- Add an HTTP Request node:
POST https://api.crabcut.ai/api/v1/clips/generatewith Header Auth (Authorization: Bearer sk_live_...) and body: - When clips are ready, the Webhook node receives the payload.
- Best clip:
{{ $json.clips[0].download_url }}
Option B — Polling loop:
POSTto generate clips (same as above, withoutcallback_url).- Wait 15 seconds → GET
https://api.crabcut.ai/api/v1/projects/{{ $json.project_id }}→ IF status is notcompleted, loop back to Wait.
