Once the task is completed, the platform will send a POST request to the `callback_url`. The request body contains the `data` field from the synchronous response plus the same `task_id` / `trace_id` / `started_at` / `finished_at` / `elapsed` fields. ## Error Response ```json theme={null} { "success": false, "task_id": "550e8400-e29b-41d4-a716-446655440000", "trace_id": "550e8400-e29b-41d4-a716-446655440001", "started_at": "2026-05-02T10:30:00.123Z", "error": { "code": "timeout", "message": "page load timed out after 30000ms" } } ``` Error codes: `bad_request` / `forbidden` / `too_many_requests` / `not_found` / `api_error` / `timeout` / `unknown` / `busy`. ## Example ```bash theme={null} curl -X POST https://api.acedata.cloud/webextrator/render \ -H "Authorization: Bearer $API_KEY" \ -H "Content-Type: application/json" \ -d '{ "url": "https://example.com", "wait_until": "networkidle", "block_resources": ["image", "media", "font"] }' ```
