IPN history problems

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

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?

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?

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.

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?

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. :dontgetit

Logs are fine too.

Is that an error on PayPal's end maybe?

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

INVNUM has nothing to do with IPN handling.

Darn, I'm totally wrong then. Where exactly do IPNs get linked to the actual transactions, that's the major problem anyway. Maybe session variables get cleared before transaction is sent to PayPal or something like that?

I'm still not clear on what the problem is. The information in the Admin->Customers->IPN History screen is reference-only. It is not used anywhere else. If the information is wrong for some reason, it's not influencing any functionality anywhere else. While it might be irritating that the information there seems to be incorrect, I'm confused why you're focused on spending time on this topic when you could be focused on building your business and generating sales.

I know that information is not crucial, but the problem is that refunds from within Zen Cart do not work any more, which is quite useful. This feature relies on working IPN message if I'm not wrong.

I always get that error when I want to do a full refund:
There was a problem refunding the transaction amount specified. (7 Field format error: 10004-The partial refund amount must be a positive amount)

So, the real problem is something about refunds, and specific error message, but you started this whole discussion by talking about IPN problems, and never mentioned the actual error message?

Sure, support here is offered at no charge to your wallet ... but ... starting with the actual issue might cause less frustration and get usable results faster.

:frusty:

Well, it's not just that refund-problem that irritates me.

For some reason the shopping cart contents do not show for the transactions on the paypal.com-website. It only shows the name of the customer, that's it. 2 days ago that worked as well.

I thought IPN is the culprit here, that's why I thought it might be a good idea to solve the root of the problem instead of coming up with 2 bugs caused by another bug.

Anyway, you were right, so
