About Universal Commerce Protocol (UCP) integration in Merchant Center

This document guides participating merchants through UCP integration in Google Merchant Center.

  • Availability: this feature is visible only to pilot merchants in the US.
  • Scope: applies only to products sold within the US.
  • Updates: additional features will be released incrementally.

Benefits of UCP integration functionality in Merchant Center

The UCP integration in Merchant Center lets you configure your settings by yourself. It provides you tools to configure your account, test your API integrations, and declare your readiness to go live.

  • Real-time testing: test your UCP integration in real-time within the Merchant Center in sandbox and production environments.
  • API endpoint validation: verify that your endpoints for checkout operations (such as creating a checkout, updating shipping settings, or completing a transaction) function correctly.
  • Check UCP implementation status: monitor functionality status post-implementation and stay up-to-date with upcoming features and product enhancements.

Eligibility and requirements

The Merchant Center onboarding experience will be gradually available in the US in the coming months during this early access program phase.

If you work with a third-party service provider or platform, connect directly with them to learn more about their plans for UCP integration.

The checkout feature enabled by UCP is available for select merchants at this time. If you'd like to express interest in participating in this early access program, submit this interest form, and complete the required technical implementation. Only product listings using the native_commerce product attribute will display the Buy button for this checkout experience. See detailed product data implementation.

Contact Support

For technical support related to UCP, use the contact form in Merchant Center. Email support is available Monday to Friday.
