//We assume you have complete a Sale or retreived a Sale Response using History query/search. 
//Note: having a valid Sale Response object is mandatory for the steps below.

//If you want the receipt for a payment you know its id (instead of the whole Sale), you can get the saleResponse of that subPayment by using the function:
//let subPaymentResponse = saleResponse.paymentForReceipt:yourPaymentId
