n8n HTTP API QA: Queue Consent-Checked Video BG Removal

Queue consent-checked video background removal and generate a QA manifest in n8n

This n8n HTTP API workflow batches up to five consent-checked video background-removal jobs, submits them (or runs an offline demo), polls for completion, and produces a per-job QA manifest that flags whether alpha/transparency and audio metadata look ready for human review.

What this workflow does

• Runs manually to load configuration defining the provider base URL, processing mode (demo vs live), and a list of background-removal jobs.
• Validates each job before any submission: rights confirmation, video URL, duration, background settings (transparent/blur/color), and edge mode.
• Builds provider payloads for each job with a stable idempotency key and the requested output options.
• Demo mode: simulates a completed result including alpha metadata—no external API calls.
• Live mode: submits each job once via POST /jobs using header-based authentication, then classifies the submit response.
• Polls for completion with bounded retries: every 15 seconds via GET /jobs/{jobId} while queued, up to a capped attempt count.
• Performs QA checks on the provider response to flag transparency/alpha readiness and whether audio appears preserved.
• Outputs a QA manifest per job with result URL, attempt count, and review notes.

Use cases

• Review-ready pipelines for SaaS operators processing multiple customer videos with transparent background outputs.
• Automation engineers testing an HTTP API background-removal provider using a safe demo mode before enabling live paid processing.
• Ops workflows that require human-in-the-loop QA based on alpha/transparency and audio metadata quality signals.

Technical details

• Nodes/tech used: if, set, code, wait, sticky note, http request.
• HTTP endpoints: POST /jobs and GET /jobs/{jobId} with header-based auth.
• Polling cadence: 15-second intervals with a capped retry loop.
• Outputs: a per-job QA manifest including attempts, result URL, and review notes.
