Google Merchant API Migration Kit for Shopify Integrations

Compatibility

Runtimes: Node.js 22.12+
Frameworks: Framework-neutral (Shopify reference adapter included)
Libraries: No required Google client library (injected transport boundary)
API versions: Google Merchant API v1, Content API for Shopping v2.1 (legacy detection and migration source)
Requirements: Existing Merchant Center production account with verified website, Google Cloud project with suitable Merchant Center permissions, Valid Google OAuth or service-account credentials for the host, Buyer-owned legacy Content API implementation to route away from
Skill level: Intermediate TypeScript, Shopify Admin API, and Google Merchant Center

Best fit

You or your team can inspect an existing repository
That repository directly calls shoppingcontent.googleapis.com, content/v2.1, the legacy shoppingContent client, or equivalent Content API methods
The integration runs in a compatible Node.js/TypeScript host you can access and deploy
You need to preserve custom product, inventory, or business logic a managed connector would not replace
You, a coding agent with the included AI workflow, or your developer will adapt, review, test, and deploy the migration

Not a fit

Shopify's Google & YouTube app or another managed provider owns the connection
A third-party feed or application provider owns the API integration and you do not own that code
There is no buyer-owned source repository that directly calls Content API
You want a hosted or no-code feed service rather than adaptable TypeScript source
You expect the download alone to perform the migration without integration work

May require adaptation

Non-TypeScript hosts that cannot adapt reference adapters
Integrations outside product, inventory, and primary data-source scope

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.
