you can use .NET SDK for Pay flow Pro classes your application sends a transaction request to a Pay flow Pro host  where Pay flow Pro server pro cesses the request and then sends back a transaction response to your application to notify you of the transaction status. In the request and response cycle a credit card transaction is accomplished and funds are moved in or out of your bank account that is linked to your Pay flow Pro payment gateway account. For testing : pilot-pay flowpro . paypal .com For pro duction: pay flowpro . paypal .com Transaction Request TRXTYPE=S&TENDER=C&ACCT=5105105105105100&EXPDATE=1209&CVV2=123&AMT=99.00 &FIRSTNAME=John&LASTNAME=Smith&STREET=123 Main St.&CITY=SanHose &STATE=CA&ZIP=12345&COMMENT1=Reservation&USER=MyUser&PWD=MyPassword &VENDOR=MyVendor&PARTNER=MyPartner Transaction Response RESULT=0&PNREF=EFHP0D426A53&RESPMSG=AP PRO VED&AUTHCODE=25TEST& AVSADDR=Y&AVSZIP=N&CVV2MATCH=Y pro tected void btnSubmit_Click( object sender EventArgs e) { try { string PayPal Request = TRXTYPE=S //S - sale transaction + &TENDER=C //C - Credit card + &ACCT= + txtCardNumber.Text //card number + &EXPDATE= + ddlMonth.SelectedValue + ddlYear.SelectedValue.Substring( 2  2 ) + &CVV2= + txtCvv.Text //card validation value (card security code) + &AMT= + txtAmount.Text + &COMMENT1=My Pro duct Sale + &USER= + ConfigurationManager.AppSettings[ USER ] + &VENDOR= + ConfigurationManager.AppSettings[ VENDOR ] + &PARTNER= + ConfigurationManager.AppSettings[ PARTNER ] + &PWD= + ConfigurationManager.AppSettings[ PWD ]; // Create an instance of Pay flow NETAPI.
