Summary
You can use the following steps to manage an existing merchant account. This
might be your own merchant account, or a client's merchant account.
Manual steps
Here are the ways you can administer a sub-account:
Administrative user (recommended)
If you need to use the Merchant Center UI, the
merchant can add your Google account as an administrative user for their
Merchant Center account.
Service account (recommended)
If you don't need the Merchant Center UI, you can authenticate through
a service account, then add the service account ID
as a user on the merchant's account.
Full management (not recommended)
We recommend one of the preceding options unless you only need to manage one
sub-account.
If the merchant wants you to fully manage their Merchant Center account and
you have an MCA, you can do the following:
Gather the IDs for your MCA and for the merchant's account.
In the top right menu bar, click the ? question mark > Help center
and support > Contact us.
Request to convert the merchant's account to a sub-account of your MCA,
and provide the ID of your MCA account and the ID of the merchant's
account.
You can contact Google again to undo this process.
Automatic steps
You can use the Content API for Shopping to request, approve, and remove links
between your MCA and other Merchant accounts. Here are the steps:
