You can authenticate with an MCA to manage sub-accounts without setting up
authentication for each sub-account. MCAs can’t have product information
themselves, so you need to create sub-accounts for merchants that have their
product information.
You can create sub-accounts manually or through the Content API for Shopping as
described in the following sections.
By default, MCAs can manage a maximum of 50 sub-accounts. If you need more than
50 sub-accounts, you can request more with the quota form.
Choose the Terms of Service for the merchant's country and language.
The Terms of Service links don't work in an iframe. You may need to send the
merchant a stored copy of the Terms of Service and have a way to keep your
copy up to date.
Keep a record of the acceptance of the Terms of Service and be prepared to
provide these records to Google if requested.
