This endpoint captures the reserved funds of a pre-authorized payment. You can confirm the full reserved amount or a partial amount less than or equal to the original pre-authorization.
If you specify an amount lower than the original pre-authorized amount, only that partial amount is captured and the remaining funds are released back to the customer.
