The Merchant Center integration is rolling out gradually in the U.S., Canada, and Australia in the coming months. This will allow you to onboard to the program from your Merchant Center account. To participate in the program:
- Complete the technical implementation as outlined in the UCP developer guide. This is necessary before you begin onboarding.
- Fill out the interest form here.
- As soon as you’re selected to participate, we’ll notify you, and then you’ll have access to the onboarding experience in Merchant Center. There, you’ll also be able to access a sandbox environment to validate your integration, including your UCP profile, identity linking, and native checkout APIs.
In addition to these validations, Merchant Center will alert you if any actions are needed to update your feed attributes, returns, or account configuration.
Note: You may see this UCP integration tab in your Merchant Center account as the onboarding experience rolls out in the coming months in the US.
