Integrating Paypal Test account in asp.net mvc

Thanks for your answersir..please look at my code below:

 

//Model 

 

//Controller 

 

 

Where is the problem?? 

Long back i have written in c#

 

Before testing my code, I log in the PayPal Developer Central and then I launch the SandBox for the seller’s email

( [email protected] ).

I would like to get some help to find out why my code is not working in the PayPal SandBox.

It returns an error message:

“We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to solve the problem.”

The strange thing is that I used the same variables and its values and the same email addresses in the PayPalTech – Testing page ( http://paypaltech.com/Stephen/test/index.htm ) and it works.

Here is the relevant code:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

// Create the PayPal redirect location for Buy Now

string redirect = "";

redirect += "https://www.sandbox.paypal.com/cgi-bin/[email protected]";

redirect += "&cmd=_xclick";

redirect += "&invoice=" + orderId;

redirect += "&item_name=" + productName;

redirect += "&item_number=" + productID;

redirect += "&amount=" + price;

redirect += "&quantity=" + quantity;

redirect += "&currency_=USD";

redirect += "&return=http://83.35.154.61/SI/PDT_CustomerReturn.aspx";

redirect += "&cancel_return=http://83.35.154.61/SI/Cancel.aspx";

redirect += "&rm=2";// means method=POST

redirect += "notify_url=http://83.35.154.61/SI/IpnHandler.aspx"; //receive IPN

redirect += "&no-shipping=1"; // not asked for shipping details

redirect += "&first_name=" + firstname;

redirect += "&last_name=" + lastname;

//redirect += "&email=" + email;

redirect += "&email=stephen@a_web_site.com";

// Redirect to the payment page

Response.Redirect(redirect);

 

hope it would resolve your problem,ensure u have properly provided amount,price string as formatted in their code
