Yeah, I've seen that. Fields ending with _date are not listed in form.fieldnames.
Curiously enough, this bug was already in CF 5, but Paypal would accept the
verification anyway.
I added the date fields, but it still doesn't work under cf9
It is really a shame Paypal does not give any detail while in test mode about WHY
the request is
invalid.

There are two dates the come over encoded but aren't when you look at your
string back that caused my issues initially and only when i outputted each
form value and looked at the resulting string did I see the issue. I forget
which ones they are and I'm not able to look at our listener right now,

I'm pretty sure its it some sort of encoding problem.
I've found this on the Paypal site:
"PayPal's IPN server expects that your script will POST back all variables that
were posted to it and more importantly, that they are encoded the same way as
they were sent to your script. If your script inadvertently changed the encoding
of a character or interprets an encoded character as another character and POSTs
back, you will likely see INVALID."
Under CF5, everything was iso-8859-1 by default, now it is UTF-8.
I can see "Charset UTF-8 " in the CFHTTP data, but there is also charset =
windows-1252 in the form fields sent by Paypal.
I checked, and the same template still works under
CF5.

As someone who is working on a new PayPal integration and has run into the
same issue as you, make sure all form fields are lower case. I seem to
remember CF defaulting to upper case in the transition to MX,

Not easy to to. The template is called by the Paypal server for every
transaction.
The template should return all form fields IN SAME ORDER in another CFHTTP
request to Paypal.
If everything looks fine, Paypal returns VERIFIED, other wise it returns INVALID.
This template that I developped myself has been working fine for years, so I
suspect the problem is not with Paypal.
CF 9 must be doing something wrong in the HTTP
request.

Things have changed a lot since CF5 and there is likley to be a fair few
things that no longer work the same.
If you cfdump the cfhttp results in CF5 and CF9 and compare them then you
will see the difference.
If you are using a 3rd party tag then there are more up to date ones you
could use instead, take a look on www.easycfm.com for a tutorial to help you
fix your existing code, or take a look at www.riaforge.org for an open
source solution or www.cftagstore.com for a commercial solution.

Hi, I recently upgraded an old CF site from version 5 to version 9.
Since then, my Instant Payment Notification from Paypal is broken.
It CFHTTP the Paypal server, but the response is now INVALID instead of VERIFIED
as it used to be.
There must be something changed in the CFHTTP which makes the request look bad to
Paypal.
I don't know with which version since CF5 this would happen.
Has any one encountered any similar
problem?
