On an approval store (store.get answers applicationEnabled: true), starts an application for a buyer account under a requestId of your own, and answers the form to show: the fields, the documents to accept and the uploads allowed. The same requestId continues the same application.
Who may call it: Anyone with the API key and the storefront host; no buyer or guest token is needed.
