Capture Specific Payment

Manually authorizes and charges the amount specified to a payment on the order. The payment must have an awaitingPreAuth status. The payment is applied against the order total (including shipping, taxes, etc.).

This endpoint enables you to delay the payment capture process. Normally, Bold Checkout adds payments to the order with a preAuthed status, indicating they have already been authorized for the given amount. When Bold is set up to only verify the payments, each payment is added to the order with a awaitingPreAuth status.
