We have the ability to use a Payflow Pro account to handle credit card transactions in our software, and one of our customers sent us an email that was sent to them from PayPal and I am just trying to figure out if this affects Payflow Pro accounts as I do not see any information relating to a certificate in our code. The code appears to be a post to their web service. I have performed a test with posting to their Pilot URL, but I am not sure that would be sufficient and want to make sure that we are covered when the official switch occurs. The code base is VB6 utilizing WinHttpRequest to perform the post in most cases, and there is also a smaller percentage that would post utilizing the Pay Flow Pro Com Control dll. Can anyone confirm whether or not Payflow Pro will be affected or provide any additional suggestions for testing purposes?
In keeping with industry standards set by the Certification Authority/Browser (CA/B) Forum, PayPal will discontinue supporting 1024-bit key length certificates and will migrate to 2048-bit certificates before the end of 2013. We have completed the installation of 2048-bit certificates for all API endpoints in our PayPal Sandbox and Payflow Pilot environments, and we will be doing the same for our production environments starting on August 5, 2013. A complete upgrade schedule is available here. We strongly encourage merchants to thoroughly test any existing integration(s) in the PayPal Sandbox and/or Payflow Pilot environments to ensure this migration will not cause any unforeseen issues.
