IPN history problems

[p1lot]

Hey folks,

I'm successfully using PP Pro with PP Express.

I receive paypal as well as CC payments, but the ipn messages are incomplete.

either the amount is missing (paypal-transactions) or the customer name is missing (creditcardcard-transactions). See attached screenshot.





I also can't do refunds from withing Zen Cart, so I assume there must be a configuration error either in my PayPal or in my Paypal modules in zen.

Anybody know what's going on here? Or should I just disable IPN in my Paypal?


I also tried to contact PayPal support, but they couldnt help me. That's what the PP-guy said.

In your screen shot you sent I see there is a transaction ETGP5EE4F60A that appears to not have received an IPN message. This transaction is your PayFlow transaction id which does not use IPN, the corresponding transaction in your PayPal account for this transaction is 5CX29628VU5428804. As you can see you do have an IPN for 5CX29628VU5428804. To me this appears to be an issue with your shopping cart not correctly linking your PayPal IPN messages back to your PayFlow transactions.




Thanks in advance

That's quite possible.

What exactly would that solve?

I actually don't know what's going on here and just quoted the response from the PayPal-guy, so I was asking for a workaround or a fix.

Disabling IPN wouldn't solve anything, but better than a half-working solution. At least that's what I think.

DrByte, do you think there is a solution for that problem? I checked some transaction logs and they all look fine.

Am I the only one with that issue?

[DrByte]

The IPN History screen you're referring to is simply a display of IPN data received. It has no functionality capability of any sort.
What particular problem is the IPN history creating for you?

[p1lot]

Well, the amount of those transactions was never "0".

Also, some information on the left side, the customer name, is missing.

The first few transactions worked fine. They looked like this.

Furthermore, refunds, which worked yesterday from within Zen Cart, stopped working today as well.

The correct Trans IDs start all with numbers, whereas the "broken" ones always with 2 letters.

[DrByte]

What changed on your site between yesterday and today, between when things were working as expected and when they stopped?
Addons installed? Modules enabled/disabled? etc?

[p1lot]

Not really, I only installed Sales Report Mod, but that has no impact on PayPal I guess.

I played a bit around with PayPal-settings etc, but nothing major and they are all exactly like yesterday.


Logs are fine too.

Is that an error on PayPal's end maybe?

[p1lot]

I think that problem occured after I got Cardinal to work.

The "old" transaction from 1 day before I went live are perfectly fine and include the shopping cart contents on the paypal site etc, new ones imss all that info.

DrByte, any idea what could be going on here?


EDIT: AHHH, the Invoice IDs get cut off by somebody all of a sudden (that didnt happen to transactions 2 days ago), that's why the PayPal support said they dont get linked to the IPN properly. Any idea why that is?

OK i think i found the source of the problem:

This is a PP express transaction and the INVNUM is missing here. Now I just need to find out why that happens.

The INVNUM is set for CC transaction, but for somereason the name of the buyer doesnt get displayed in the PayPal IPN section under ZenCart admin.

Anybody else had this problem? It's pretty similar to this one: http://www.zen-cart.com/forum/showthread.php?t=139389
