Purchase

The purchase command allows you to initiate a transaction for an amount equal to the totalAmount specified in the request body.

Additionally you can separate the transaction into several smaller ones which is know as a partial transaction. This can occur when a customer uses a gift card with a remaining balance below the total purchase amount, in which case, subsequent transactions must be initiated until there is no remaining amount in the response. The initial transaction in the partial transaction flow will return a remainingAmount value that will be sent in follow-up transactions to bypass the tip select screen so customers aren't prompted to give a tip for each transaction.
