Hi Team,
I run a 2-payment transaction code for stripe platform and i getting following error :-
| System.ArgumentNullException: Value cannot be null. Parameter name: hostname at System.Net.Sockets.TcpClient..ctor(String hostname, Int32 port) at ASP.cs_sock_2party_aspx.Page_Load(Object sender, EventArgs e) in d:\certifications\MCSD\codes\practicals\Payment\2party payment\CS_Sock_2party.aspx:line 497 |
Can anyone help, I am very new for payments implementation

Any information passed through the customer's browser

fraudulently alter the transaction data. Therefore all transactional

a way that could potentially be modified (e.g. hidden form fields).
Transaction data should only be accepted once from a browser at the
point of input, and then kept in a way that does not allow others
to modify it (e.g. database, server session, etc.). Any transaction
information displayed to a customer, such as amount, should be passed
only as display information and the actual transactional data should be
retrieved from the secure source last thing at the point of processing
the transaction.</p><p class='blue'>Fields like return links back to the order page (AgainLink),

information are only included here in the example for information purposes.
