You can increment the auth amount of a previous :magic-link[Auth Only]{id="auth-only"} transaction. You will need to use the unique transaction identifier returned in the response to the Auth Only transaction.

You must still use :magic-link[Pre-Auth Complete]{id="auth-convert-sale"} to convert the transaction to a Sale or use :magic-link[Auth Only Reversal]{id="auth-only-reverse"} to delete and restore the funds in the card. Note that you must still use the unique transaction identifier of the original Auth Only transaction to perform either one of these actions.
