This function is used to create a set of Purchases for a Customer. By default, the Purchases will be added in Draft status and must be finalized before it charges against the Customer account. Optionally, you can set these purchases to auto-finalize and purchase immediately.
Note, the Purchases key/value is a nested list which allows you to post any number of purchases as its own list.
