The Account Application is used to make the final submission when applying to open a new account. Each Account Application that you create requires the inclusion of the IDs of the relevant Account Product, Business Application, Person Application(s), and Deposit objects. Both consumer and commercial account applications are submitted via this endpoint. The shape of each varies slightly.
The person_applications parameter is only required for consumer accounts; a similar parameter is available on the Business Application object for commercial accounts.
