We have had some customers contact us regarding the email notifications they have received from PayPal. These notifications discuss the deprecation of certain Payflow URLs. As this pertains to our X-Cart customers, if you have a store utilizing X-Cart version 4.3.x or older AND use Payflow Pro as a payment processor, you will need to have a patch performed to continue processing payments with your current set-up.
If you have specific questions related to this change, PayPal suggests to contact your Technical Account Manager or Partner Technical Support for assistance at www.paypal.com/mts. Of course, if you are looking for assistance in having this patch performed before the August 3rd deadline, please reach out to us at www.bcsengineering.com/contact_us/.
