Problems with PayPal IPN

[tslav]

I am having trouble implementing ZenCart PayPal IPN payment module on my store.

Ordering goes smoothly. user is directed to PayPal order section. After the user completes his order he is directed stright back to the store's success page. The user's Paypal account is being charged with the exact amount and the store receive the payment. However, I cannot see the order in the store's admin section (either on Orders, PayPal IPN.)

Moreover, when user is directed to the success page there is no "Order ID".
Also, Paypal order description is "zenid=qs519uteiiebgrpheov4co9ij1". Shouldn't it be the complete order description?

After checking the log files I encountered with the following error :

Aug 20 2008 11:14 -- IPN INFO - Confirmation/Validation response


FAIL

After going through the forum I have tested the communication with IPNcheck.php, Curltest.php. Both seems to be working well.


Hope you could assist me resolving the issue.

Hey all,

paypal has a list of the IPs that they use,
you might want to see if you can find this list and send it to your host,

we had an issue the otherday where paypal was actually caught by our firewalls and locked out,

that would of course stop the IPN from working

At the surface, I see two possible causes:
- Merlin's point about blocked IPs
- Maybe you've got a bad PDT setting in your store vs your PayPal profile.

You can find PayPal module setup and troubleshooting instructions, as well as a list of known PayPal server IP addresses here: http://www.zen-cart.com/wiki/index.php/PayPal

[tslav]

Well, I have some progress regarding that manner (After wasting half a day ).

First, it is not a firewall issue. I have allowed all pay pal's IP address and I get data from PayPal's servers.
Second, the PDT number seems to be OK. I have double checked it.

Please take a look at my access_logs on my server (Right after the user finishes his purchase with pay pal):

### PayPal Data to handler
66.211.170.66 - - [21/Aug/2008:15:18:17 +0300] "POST /ipn_main_handler.php HTTP/1.0" 500 - "-" "-"
66.211.170.66 - - [21/Aug/2008:15:18:29 +0300] "POST /ipn_main_handler.php HTTP/1.0" 500 - "-" "-"
### END

#### Refering back to site (This is done successfully (though the order id parameter is blank )

- - [21/Aug/2008:15:18:29 +0300] "GET /checkout_process/referer/paypal? ....

### END

few questions here ... Why the POST has 500 error code? Why it replay's with empty data?

[DrByte]

If your server is causing the ipn_main_handler.php file to trigger a 500 error, you'll have to deal with your server administrator to find out the cause. "500" errors are defined by the server, not Zen Cart.
