PayPal IPN is very hard to crack indeed. This code is working!!! Before you start, I think there is a problem in general with the way various versions of coldfusion decodes and encodes strings. Writer Pablo's code for instance is not working for me because when you examine the encoded string, there are characters missing/ changed/ moved which causes the PayPal verification to fail! The code below worked for me. Thought I'd share it for those who struggled like I did. Good luck and let me know what you think. <!-------------------------------------------------------------------------------------------------- Remember, this is not a graphic interface - The IPN.CFM file should run in the background. It is only an interface between PayPal and your transaction complete, invalid or error steps. ---------------------------------------------------------------------------------------------------> <cfset x = GetHttpRequestData()> <cfset str="cmd=_notify-validate&" & x.content> <!---post back to PayPal for validation---> <cfhttp url="https://www.paypal.com/cgi-bin/webscr?#str#" method="GET" resolveurl="no"> </cfhttp> <!-------------------------------------------------------------------------------------------------- Use the following to test your IPN.CFM file - The idea is to record the PayPal encoded and hidden 'message string' as posted by PayPal apon completion of each transaction. I record the message to a .txt file called IPN_log.txt - Make sure you change the path to the relative path of your own web direcory on the server. ---------------------------------------------------------------------------------------------------> <cffile action="append" file="d:\yourWebDirectory\IPN_log.txt" output=" ------------------------------------------------------------- Paypal Says the transaction is: #CFHTTP.FileContent# Transaction status: #FORM.payment_status# Seller account: #FORM.RECEIVER_EMAIL# ------------------------------------------------------------- " addnewline="yes"> <CFLOOP INDEX="TheField" list="#Form.FieldNames#"> <CFSET str = str & "#LCase(TheField)#=#URLEncodedFormat(Form[TheField])#"> <cffile action="append" file="d:\yourWebDirectory\IPN_log.txt" output="#LCase(TheField)#---->#(Form[TheField])#" addnewline="yes"> </CFLOOP> <!--- Payment verified ---> <CFIF #CFHTTP.FileContent# is "VERIFIED"> <!-- check that payment_status=Completed --> <cfif #FORM.payment_status# eq "Completed"> <!-- check that receiver_email is your email address (that money went into your account --> <cfif #FORM.RECEIVER_EMAIL# eq "name@email.com"> Paypal says the funds went into your account<br> <!-- Everything checked ok, add your action here (typically you would want to update your database here --> </cfif> </cfif> <CFELSEIF #CFHTTP.FileContent# is "INVALID"> <!-- The information is not valid, please investigate and trace invalid info --> Invalid Info<br> <!---Something that was purchased was invalid, either the order or the information provided. This is usually good to log in case someone is trying to purchase with stolen card numbers, etc. Here simply place a QUERY tag that insert the data above into a database.---> <CFELSE> <!-- ERROR --> <!---This usually means that something went wrong along the way, you can use this area to log it and keep for your records.---> </CFIF>

You can set the return url but not aware of a redirect variable that affects the button. Why don't you set a variable on the return url so as to pick up the session, if that's what you're doing? Let the ipn enter it in the db.

Hey, have you tried your script with this test page:

I always get an "invalid" response and think it must be their server. Can you point your script there and try and let me know?

Hey!
I have been trying for so long now to find some code to use Paypal IPN with Multi-Item Transactions. I can only get 1 item to go into my DB and not (for example) 3 items.

I am willing to pay, or donate to anyone who can help me get code to make this work with Multi-Item Transactions.

Basically when someone buys 3 items at a time on my site, I want to log them all in my DB, and not just one (prefered 1 per row in the table)

Please contact me Sirseth@sympatico.ca

Thanks!
