Question on ASP and worldpay callback

[michdoh]

HI all

I wondered if anyone can give me some advice on wow to deal with the
call-back process generated by Worldpay.

My understanding is that after a transaction Worldpay will send the
result's to a specified URL. All of the scripts I've looked at parse
the query string and display the data onto a web-page, which obviously
renders a page, as there is no one to read this and it does not go to
the client I'm not sure what use these scripts are.

I have a couple of general ASP questions if anyone has a solution

How do you make a call to an asp page that updates a database but does
not render a page? I'm probably being dumb but what does the url look
like? I.E can I make a call direclty to a web-service to update my DB.

I'm running dot.net framework 1.1, MCMS 2002 and using visual studion
202

Any thoughts are greatly appreciated

Mikey

Hi

the callback script is simply an ASP page that does not have any html.

basically the callback from world pay is used to:

get data from the posted variables
save to a database
send an email or two.

the url looks the same as any other url - but dont make it something that
other visitors to your site can go to.
the first thing the page should do is ensure that it is being called by
worldpay - i.e. do a transaction=yes check

a page that makes a call to a database - does not show anything on the page.
e.g.

' has transaction occured?
if Request.Form("transStatus") = "Y" then ' from world pay

' save to database
dim rs, c, orderid, sql
buyerid = Request.Form("cartid")
wp_id = Request.Form("transId")


c = orderdb
set rs = server.CreateObject("ADODB.Recordset")
sql = "insert into payment_t (TransID, BuyerID, Email, AmountPaid, DT)
values ("
sql = sql & "'" & wp_id & "','" & buyerid & "','" & buyer_email & "'," &
Request.Form("amount")
sql = sql & ",#" & mydate(now()) & "#)"

rs.Open sql, c
set rs = nothing
