numberOfSeats property

This is a required property and is exclusive to subscriptions with ANNUAL_MONTHLY_PAY and ANNUAL_YEARLY_PAY plans.

This property sets the maximum number of licenses assignable to users on a subscription. The reseller can add more licenses, but once set, the numberOfSeats cannot be reduced until renewal. The reseller is invoiced based on the numberOfSeats value regardless of how many of these user licenses are assigned. *Note: *Google Workspace subscriptions automatically assign a license to every user.
