Redirect to page after payments in Paypal

Hi vereato,

To set return url from code behind you need to set the return QueryString value in the url you are requesting.

Check the below example.

C#

string payPalUrl = "https://www.paypal.com/us/cgi-bin/webscr";
string paypalEmail = "paypal@gmail.com";
string successURL = "http://localhost:4076/Success.aspx";
string failedURL = "http://localhost:4076/Failed.aspx";

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.AppendFormat("{0}?cmd=_xclick&business={1}", payPalUrl, HttpUtility.UrlEncode(paypalEmail));
// Currency.
sb.Append("&lc=US&no_note=0&currency_code=USD");
// Product Name.
sb.AppendFormat("&item_name={0}", HttpUtility.UrlEncode("Tube Light"));
// Invoice number.
sb.AppendFormat("&invoice={0}", "12345");
// Product Amount.
sb.AppendFormat("&amount={0}", "200");
// Product Quantity.
sb.AppendFormat("&quantity={0}", "5");
// Product Number.
sb.AppendFormat("&item_number={0}", HttpUtility.UrlEncode("12345"));
// Return Url.
sb.AppendFormat("&return={0}", HttpUtility.UrlEncode(successURL));
// Failed Url.
sb.AppendFormat("&cancel_return={0}", HttpUtility.UrlEncode(failedURL));
Response.Redirect(sb.ToString());

VB.Net

Dim payPalUrl As String = "https://www.paypal.com/us/cgi-bin/webscr"
Dim paypalEmail As String = "paypal@gmail.com"
Dim successURL As String = "http://localhost:4076/Success.aspx"
Dim failedURL As String = "http://localhost:4076/Failed.aspx"
Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
sb.AppendFormat("{0}?cmd=_xclick&business={1}", payPalUrl, HttpUtility.UrlEncode(paypalEmail))
' Currency.
sb.Append("&lc=US&no_note=0&currency_code=USD")
' Product Name.
sb.AppendFormat("&item_name={0}", HttpUtility.UrlEncode("Tube Light"))
' Invoice number.
sb.AppendFormat("&invoice={0}", "12345")
' Product Amount.
sb.AppendFormat("&amount={0}", "200")
' Product Quantity.
sb.AppendFormat("&quantity={0}", "5")
' Product Number.
sb.AppendFormat("&item_number={0}", HttpUtility.UrlEncode("12345"))
' Return Url.
sb.AppendFormat("&return={0}", HttpUtility.UrlEncode(successURL))
' Failed Url.
sb.AppendFormat("&cancel_return={0}", HttpUtility.UrlEncode(failedURL))
Response.Redirect(sb.ToString())
