Hello,
I have get an email that It says, before 31 may I have to change to TLS 1.2 y http/1.1. My project is made with C# .NET and I have upgraded to 4.5 .NET version. Then I have updated my web service from paypal https://www.paypal.com/wsdl/PayPalSvc.wsdl. Then I have added this line to the project, before the web request:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
But when I call ClientePayPal.SetExpressCheckout(ref HeaderType, req)
It sayes this message "Could not create SSL/TLS secure channel with api-aa.sandbox.paypal.com"
Anybody know why? What I have to make?
I have verified in my machine .Net and TLS1.2 and It returns always:
PayPal_Connection_OK
So, any help?
Thank you,
Regards
