Providing the Personal Shopper Information

The value in the retrieveDetail request must be equal to the following calculation from the

retrieveDetailResponse (in pseudo code):

value = 0;

for each (InvoiceLine in lines) {

value += (itemPrice + itemVAT) * numberOfItems ;

}

totalValue = value;

Figure 2: Pseudo Code for Calculating the Total Value of the Invoice Lines

Please note that if the total value of the retrieved invoice lines is not equal to the amount that was requested

an error will be displayed to the shopper. This means that the transaction ends and can not be completed!
