On January 4, 2010 Payflow Pro Software Development Kits (SDK) versions 2.xx, 3.xx, 4.0x and 4.1x are expiring permanently. There are still some merchants who have yet to update their systems to Payflow Pro SDK version 4.3 or higher. If you are still using an outdated SDK, you must update your integration as soon as possible. There is no charge for the new software.
To prepare for this change, we are performing system readiness testing on October 22 and October 29 for one-hour, between 8:00 A.M and 1:00 PM PDT. During this time, all transactions submitted using an outdated SDK will fail. Failed transactions will receive result code 131: “This SDK version is no longer supported; contact Payflow Support.”
We will notify affected merchants 10 days prior to these interruptions via email. Again, if you are still using an outdated SDK, it is very important that you update your integration immediately.
For simple step-by-step instructions on what to do, call 1-877-729-7258 or visit www.paypal.com/gatewayupdate.
If you have any questions please contact our support team at payflow-update@paypal.com.
