Create an Aeropay Transaction Object where funds will move from a user to a merchant.

The userForMerchant authorizationToken specifies the paying user. The merchant being paid is specified by the merchantId in the request body. The user's default bank account will be selected if no bankAccountId is specified.

Amount is specified as XX.XX in dollars. An optional description may be provided.

A merchant must generate and pass a uuid (following standard uuid guidelines in ISO/IEC 9834-8) to associate the transaction with an internal system.

Attributes are AeroPay formatted data that you may wish to include with your transaction. For example, an invoice number or the tracking of a tip amount.
NOTE: Tip amounts will be added to the 'amount' value.
