Incremental Authorizations

Incremental authorizations are useful when a customer adds products and services to a purchase. After a successful initial authorization, you can request subsequent authorizations and request one capture for the initial authorization and the incremental authorizations.

The incremental authorization service is not the same as the incremental authorization scenario for a merchant-initiated transaction.
