An “authorize” is the first part of a two-par sale. Generally, an authorize will check the validity of the account, amounts, etc. in the transaction and may put a hold on the funds in the account. The “authorize” call must be followed by a call to “capture” in order for the sale to be complete. Any “authorize” that is not followed by a corresponding “capture” will consider the transaction to have been voided.
