New Merchant Center Connection - Account Creation

Introduction and Business Impact


There are more specific steps to be aware about when creating new Merchant Center accounts on behalf of your merchants through your integration.

UX Guidance


A merchant center account is required. If there is no pre-existing one, then the merchant needs to create a new one. They can create a new MC account when they have multiple or single pre-existing ones. Always surface the CSS disclaimer whenever merchants are about to create a new MC account.

New Merchant Center Account Creation

When your merchant does not have a Merchant Center Account, they are prompted to create a new one: new_mc

The CSS notification surfaces whenever a merchant creates a new MC account. They click the "continue" button and they receive a confirmation that their new account has been created: css

Tech Guidance


Your merchant first needs to connect their gmail account of their preference or create a new one. Using Oauth, we recommend providing the ability through your integration for them to connect their existing gmail account or create one. Learn more about how to set up Oauth for the Paid ads and Shopping ads integration.

To create a new account, use the accounts.insert method of the Accounts service:

  1. Authenticating as an MCA: This lets you manage its sub-accounts using the Content API without having to set up authentication for each new sub-account.

  2. Provide access to your Merchants to their MC subaccounts: We recommend you to add your merchant as an Admin and Reporting Manager user of the sub-account. You do an accounts.update request adding a new AccountUser object in the AccountUser array. We recommend adding the roles of 'Admin' and 'ReportingManager'. The merchant has to accept the ToS in this case.

  3. New merchant account ToS Acceptance Required: Don't create the Merchant Center account if the merchant does not opt-in. You need to record that the merchant has read and accepted the ToS in your backend. Update the terms of service so it can future proof any changes in our Merchant Center ToS.

  4. OAuth: We highly recommend you to use oAuth to make API calls on behalf of your merchant’s user

  5. Business information: The new merchant Center accounts should have the business names, phone number, address, and URL added (See Business Information Section)

Merchant wants to remove itself from your MCA
