Patent attributes
An embodiment includes a method of multi-leg transaction processing. The method includes receiving from a merchant server, a designation of two or more sub-transactions of a pending multi-leg transaction as a coupled group. The execution of any of the two or more sub-transactions in the coupled group is dependent on prior authorization of each of the two or more sub-transactions. The method includes receiving transaction input used to indicate conditional execution of the multi-leg transaction. Prior to execution of the multi-leg transaction and in substantially real time, the method includes determining whether each of the two or more sub-transactions in the coupled group is authorized. In response to any of the two or more sub-transactions being unauthorized, the method includes preventing execution of the multi-leg transaction. In response to authorization of each of the two or more sub-transactions, the method includes executing the multi-leg transaction non-sequentially.
