Skill level

Intermediate TypeScript, Shopify Admin API, and Google Merchant Center

Best fit

• Custom Node.js/TypeScript Shopify-to-Merchant Center integrations
• Agencies maintaining private product or inventory sync pipelines
• Headless Shopify teams that call Content API directly

Not included

• A hosted migration or synchronization service
• Automatic rewriting of buyer repositories
• A full Shopify application or Merchant Center dashboard
• Shopify's managed Google & YouTube app
• Google Ads API or campaign management
• OAuth UI, credential storage, or service-account provisioning
• Queues, databases, deployment infrastructure, or observability vendors
• Buyer-specific implementation, deployment, or support as a service

Integration notes

• Use Google's official Merchant API MCP server or Agent Skills for current API context; use this kit for its tested TypeScript components, Shopify-oriented migration structure, fixtures, tests, and rollback workflow.
• Run the scanner before editing host code and keep legacy paths until each area is accepted.
• Migrate one functional area at a time; dual writes are off by default.
• If the host does not call shoppingcontent.googleapis.com or content/v2.1 directly, this kit is probably not required.
• AI-ready documentation and agent instructions included.
