Shopify Social Auto-Post with AI Captions

What This Agent Does

This powerful automation workflow transforms your Shopify store into a social media marketing machine. When a new product is created in Shopify, the agent automatically generates compelling social media captions using AI, posts them to your Facebook page, logs the activity to Google Sheets for tracking, and notifies your team via Slack—all without manual intervention.

Key benefits and time savings:

• Eliminate manual copywriting: AI generates professional, engaging captions instantly
• Maintain consistency: Every product gets posted with the same quality standards
• Save 15-20 minutes per product: Automate what typically takes manual effort
• Create an audit trail: Every post is logged automatically for compliance and analytics
• Keep teams aligned: Instant Slack notifications ensure everyone knows when products go live

Target use cases:

• E-commerce businesses launching multiple products weekly
• Social media teams managing high-volume product catalogs
• Brands wanting consistent posting schedules across channels
• Companies requiring documented records of all social media activity

Who Is It For

This workflow is ideal for:

• E-commerce managers running Shopify stores with active social media presence
• Social media teams managing multiple product launches
• Marketing departments seeking to scale content production
• Small to mid-size businesses without dedicated copywriting resources
• Agencies managing multiple client Shopify stores

You'll need basic familiarity with API keys and platform integrations, but no coding experience is required.
