Quick overview

This webhook-driven workflow generates short-form video scripts and publishing copy with OpenAI, runs a local copy/duration audit, and renders approved 9:16 videos via Creatomate, returning either a creative kit, an audit checklist, a render job ID, or a final video URL.

How it works

  1. Receives a POST webhook request (header-authenticated) with an action of draft, audit, render, or status.
  2. Validates and sanitizes the request fields, enforcing limits and requiring explicit approval and rights confirmation before rendering.
  3. For draft requests, sends a prompt to the OpenAI Chat Completions API to generate two hooks, a 4-scene storyboard, voiceover, hashtags, and SEO metadata, then returns a validated publishing kit for YouTube/TikTok/Instagram.
  4. For audit requests, performs a deterministic local preflight to estimate duration and flag copy issues (for example length limits and exaggerated claims) and returns a checklist for human review.
  5. For render requests, submits the approved Hook, Supporting_Text, and CTA into a specified Creatomate 1080×1920 template and returns the queued render job ID.
  6. For status requests, fetches the Creatomate render job status and returns the final video URL and snapshot URL once the render succeeds (or errors if it fails).

Setup

  1. Create a header-authenticated webhook credential for the incoming request and configure the calling app to send the required header.
  2. Add an OpenAI API key as an HTTP Header Auth credential for the OpenAI request step.
  3. Add a Creatomate API key as an HTTP Header Auth credential for the Creatomate render and status request steps.
  4. In Creatomate, create a 1080×1920 template and ensure it contains elements named exactly Hook, Supporting_Text, and CTA, then use its template_id in render requests.
  5. Build your client request payloads for each action (draft/audit/render/status) and only call render with approved=true and rights_confirmed=true after a manual review.
