Hi, we are planning to implement zip/postal code verification for all credit card processing. The following SOAP API method "CheckoutEx4" accepts a zip code parameter for this purpose. Is anybody using this functionality? How is it working for you? Is there any specific setup issues that we should be aware of, also given the fact that US and Canada have a different postal/zip code format?
Our plan is to display the primary address postal code, saved in the database, during the online check out process for customer convenience. If a customer happens to use a credit card with a different billing address, then customer will have the option to edit it before it's sent out for verification.
Advance thanks for any comments or suggestions.
Best,
