We have used Payflow_dotNET.dll several years. In the past few days (after 2/17/2017) , We found we cannot process payment on Payflow Pilot Testing Endpoints pilot-payflowpro.paypal.com

We got timeout or Result=-1 Faild to connect to host Input Server Result -1

or -32 The certificate chain not validate... Result -32

We don't found any information said Payflow_dotNET.dll is NOT Working after 02/15/2017 PayPal Upgraded to TLS1.2 for Pilot Testing Endpoints.

Our question is:

  • Does Payflow_dotNET.dll no Longer works on Payflow Pilot Testing Endpoints pilot-payflowpro.paypal.com?
  • Does anyone has suggestion for us to change to use other APIs to replace it?

We had the same issue and found that you need to set ServicePointManager.SecurityProtocol to allow SecurityProtocolType.Tls12. In our case we used SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 and it seemed to work. Good luck!

We had the same problem. Had to add one line of code to my PayFlow wrapper class. Third line of the constructor here solved the problem.

public CardProcessor() {
        payFlowProUser = new UserInfo(USER, VENDOR, PARTNER, PWD);
        payFlowConnection = new PayflowConnectionData();
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
}

I believe PayPal is upgrading their security. Found a link on the same
