PayPalAPIAAInterfaceClient objpaypalapiaainterfaceclient = new PayPalAPIAAInterfaceClient("paypalapiaa");
        CustomSecurityHeaderType objcustomsecurityheadertype = new CustomSecurityHeaderType();
        objcustomsecurityheadertype.Credentials = new UserIdPasswordType();
        objcustomsecurityheadertype.Credentials.Signature = "a8ft-8ji.2tzocnfshfjj4ahgxn4avlxzply8bmsbupxafkbty2--c6p";
        objcustomsecurityheadertype.Credentials.Username = "fred_1350925179_biz_api1.gmail.com";
        objcustomsecurityheadertype.Credentials.Password = "1350925199";

        DoDirectPaymentReq objdodirectpaymentreq = new DoDirectPaymentReq();
        objdodirectpaymentreq.DoDirectPaymentRequest = new DoDirectPaymentRequestType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails = new DoDirectPaymentRequestDetailsType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentAction = new PaymentActionCodeType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentAction = PaymentActionCodeType.Sale;
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentDetails = new PaymentDetailsType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard = new CreditCardDetailsType();
        //objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentDetails.InvoiceID = "1";
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.IPAddress = Request.ServerVariables["remote_addr"].ToString();

        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CreditCardType = CreditCardTypeType.MasterCard;

        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentDetails.OrderTotal = new BasicAmountType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CardOwner = new PayerInfoType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CardOwner.PayerName = new PersonNameType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentDetails.OrderTotal.currencyID = CurrencyCodeType.USD;
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CardOwner.Address = new AddressType();
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.PaymentDetails.OrderTotal.Value = "120";
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CreditCardNumber ="1111222233334444";
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CVV2 = "258";
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.ExpMonth = 9;
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.ExpYear = 2013;
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CardOwner.Payer = "rahularyansharma@gmail.com";
        objdodirectpaymentreq.DoDirectPaymentRequest.DoDirectPaymentRequestDetails.CreditCard.CardOwner.PayerName.FirstName = "Shakti";

You can confirm the SSL protocol for https://www.sandbox.paypal.com, using https://www.ssllabs.com/ssltest. The screenshot shows that it supports TLS 1.2 enter image description here You will need to add the following two lines to your code at the point of making httpclient call:

ServicePointManager.Expect100Continue = true; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Sample: enter image description here The implementation should solve the problem.

Sorry, i cannot add this as a comment/question.

It seems like one of certificates for paypal is not in the trusted list.

Can you try download paypal root certificate and install it as trusted CA?

I think this two links can help you: https://www.sslshopper.com/ssl-certificate-not-trusted-error.html and http://raysilvadotnet.wordpress.com/2014/02/13/problema-system-net-webexception-the-request-was-aborted-could-not-create-ssltls-secure-channel/ (sorry, cannot insert more than 2 links as normal links)

Also, please make sure you authenticating via login/password not certificate. If you are using certificate for API, you should follow last paragraph of this link
