Response notes
ND001 - Hash validation
A hash string is also included in the response, so that you can implement a verification logic to make sure it was sent by Worldnet. See how to decode and validate a hash string at Special Fields and Parameters.
For this specific feature, you should expect the following format:
TERMINALID:MERCHANTREF:DATETIME:RESPONSECODE:RESPONSETEXT:SECRET
ND002 - International customers
If you want to be able to accept international payments, make sure your account has any type of multi-currency processing enabled.
The most common is DCC (Dynamic Currency Conversion), it is also the only form of multi-currency processing that adds extra steps to the cardholder experience.
When setting up a subscription for a foreign card, a decision page will be displayed where the customer has to decide whether he wants to pay in his home currency or in the terminal's base currency.
