UGC Instagram Reels from Product URLs with OpenAI + Slack

Turn any product URL into UGC-ready Instagram Reels—automatically

With UGC Instagram Reels from Product URLs with OpenAI + Slack, paste a product page link and your n8n workflow generates multiple 9:16 UGC-style video ad variants using OpenAI and Sisif. A reviewer chooses the winner in Slack, and the approved Reel gets published to Instagram via the Facebook Graph API.

What this workflow does

• Accepts a product URL from an n8n form trigger or a POST webhook.
• Fetches and parses the product page: retrieves the HTML, extracts the title, description, and cleaned page text.
• Generates UGC creative assets with OpenAI: a hook, short script, Instagram caption, and three distinct visual prompts.
• Renders video variants with Sisif: sends each prompt to Sisif to generate a 5-second 720×1280 video, polling up to 40 times for completion.
• Routes options for approval in Slack: posts the available variant links to the selected Slack channel and waits for a reviewer to choose or reject.
• Publishes the approved Reel: creates an Instagram Reels media container via the Facebook Graph API, polls until processing finishes, then publishes.

Use cases

• SaaS marketing teams that want rapid UGC-style Instagram Reels from product catalog URLs.
• E-commerce operators testing multiple creative angles without manually scripting or video-editing.
• Automation engineers building a governed workflow: OpenAI → Sisif → Slack approval → Instagram publishing.
