Dallas TX - PayPal customers using PayPro Flow Software Developers kit 4.3 or older will be required to upgrade their software by September 1, 2009 or their sites will no longer be able to process Paypal transactions. 

The upgrade should make PayPal sites more secure as they are focused on Secure Socket Layer (SSL) certificates as opposed to the old system which relied on bundled root keys.  An SSL certificate verifies that all data on the server is encrypted and thus secure and the new system will use a dual tiered system. 

Paypal says that customers who will need to upgrade have been emailed about the changes.  There is also a tool  which will allow customers to evaluate their sites and determine if they need to take steps to avoid down time.

Customer’s of Network Solutions, ASecureCart, Mals-Ecommerce Limited, ProStores and Shop Sites should not be affected as these vendors have already taken steps to do the upgrade on their servers.  Users of third party shopping carts such as Yahoo Stores, NetSuite and ProStores also need not take action at this time as PayPal is working directly with them to make the updates. 

“People should definitely be taking action now,” says Daniel Burge, President of Burada Inc. who is a Certified PayPal Developer.  “You never know if these changes are going to affect other parts of your website and October 31 is not the time to be realizing that you’ve got problems,” he adds. 

Burge says that most of his customers have already made the upgrade. 

PayPal says the changes will not affect the way the user interfaces with it’s with it’s software or control panel.  The changes are only on the server side and will be invisible to both vendors and their customers.
