Hi,
If an email address is not already associated with an AdWords account, you'll not be able to create an account using its OAuth2 credentials. If this email address is associated with a Manager account, you'll be able to create new accounts and link to other accounts using
ManagedCustomerService. Please see the
Managing Accounts guide for more information on using this service. The
CreateAccount Java example shows how to create an account under an AdWords manager account. Example code in other languages is available
here.
To link a manager account and a client account, you need to:
- Extend an invitation to the client account from your Manager account.
- Accept the invitation from the client account.
Please note that you need to know the clientCustomerId beforehand. You should ensure that you use the main MCC's
OAuth2 credentials for the first step and the sub-MCC's OAuth2 credentials for the second step.
Regards,
Shwetha, AdWords API Team.
