Hello,
I have consistently had issues with the IPN for the website – Paypal keeps sending failure notifications. The site resides in a folder but the url for pages etc does not show the directory – it is a standard directory install. I have tried setting the IPN to both
http://mysite.ie/?eo-listener=ipn&eo-gateway=paypal
and also to
http://mysite.ie/thesubdirectoryitisinstalledin/?eo-listener=ipn&eo-gateway=paypalbut both cause the ipn failure notice.
After a certain period paypal discontinues sending the IPNs and the paid for events are not registered on the backend, which is confusing. I want to correct the listener – can you confirm what it should be? It is annoying because other than getting the failure notices it is working fine (until Paypal turns the IPN off and I have to enable the IPN again).
Thanks
Charlotte KittoSeptember 17, 2014 at 4:30 pm #12627Hi Charlotte,
The url that should be used is the url to the WordPress installation with (
?eo-listener=ipn&eo-gateway=paypal
appended).So if you’re wp-admin url is
www.mysite.com/some-folder/wp-admin/
you would expect the IPN url to bewww.mysite.com/some-folder?eo-listener=ipn&eo-gateway=paypal
. You do not need to set this. Event Organiser tells PayPal the url to use, and that will over-ride any setting in your PayPal account.You mention
other than getting the failure notices it is working fine (until Paypal turns the IPN off)
Does that mean bookings are being correctly confirmed?
What is the listener url as PayPal reports it? (If you have a PayPal business account, (it’s free), PayPal will log the IPN notifications). And what do PayPal report as being the reason for the failure?
Stephen HarrisSeptember 18, 2014 at 10:56 am #12642Hi Stephen
Thanks for the response I have been on to paypal and what they are saying is that:
http://mysite.ie/?eo-listener=ipn&eo-gateway=paypal – returns a 200 okay response
http://mysite.ie/thesubdirectoryitisinstalledin/?eo-listener=ipn&eo-gateway=paypal – returns a 404 error
Paypal are saying that the cart is over-riding the http://mysite.ie/?eo-listener=ipn&eo-gateway=paypal with the one with the 404 error.
The site is set to top level despite being in a folder – you know the standard way in the main wordpress settings.
So that I think I need to change the “notify_url” in the cart to fix the error.
Is that feasible?
regards
CharlotteCharlotte KittoSeptember 18, 2014 at 11:39 am #12643Sorry in answer to your other question – yes the bookings are being correctly confirmed.
Copy and paste from the paypal messages in case you need it (URL changed obviously): – I also have the curl test result if you needed to see that….

The one set in the profile is http://mysite.ie/?eo-listener=ipn&eo-gateway=paypal.
However this gets overridden by the shopping cart, still passing http://mysite.ie/directory/?eo-listener=ipn&eo-gateway=paypal as “notify_url” on a transaction basis.

Hi Charlotte,Thank you for contacting PayPal Merchant Technical Services.
Unfortunately failure notifications can’t be stopped. We do disable the IPN service after a certain number of failures for the reliability of our system.
According to your client’s IPN history, the URL http://mysite.ie/directory/?eo-listener=ipn&eo-gateway=paypal is returning a HTTP 404 error. I got the same result with a curl post
I’m afraid the cart is not using the IPN service to update the orders as no one has been successful.
Charlotte KittoSeptember 18, 2014 at 11:52 am #12644Hi Charlotte,
Thanks, I’m going to look into this. Would you mind telling me the address of the IPN listener? (You can do so privately via this form if you prefer). You can manually change the notify url with the following:
add_filter( 'eventorganiser_gateway_checkout_paypal', 'set_my_notify_url', 10, 2 ); function set_my_notify_url( $url, $paypal_args ){ $url = add_query_arg( 'notify_url', '...new url....', $url ); return $url; }
But the fact that bookings are being confirmed suggests its the right url but the wrong headers are being returned (hence I’d like the url to check them!)
Stephen HarrisSeptember 18, 2014 at 11:53 am #12646Sorry for the stream of messages – but should line 43 of paypal-standard.php
$this->listener = add_query_arg( array( ‘eo-listener’ => ‘ipn’, ‘eo-gateway’ => ‘paypal’ ), trailingslashit( site_url() ) );
actually say
$this->listener = add_query_arg( array( ‘eo-listener’ => ‘ipn’, ‘eo-gateway’ => ‘paypal’ ), trailingslashit( home_url() ) );
to make it reference the right URL?
Charlotte KittoSeptember 18, 2014 at 11:55 am #12647Yes, but I think
site_url()
is generally speaking the correct one ashome_url()
could point to a non-wordpress generated page for example, it’s whatever you set as the “site url” in the settings (yes, confusing naming!) – see my reply above which I think crossed paths with your last post 🙂Stephen HarrisSeptember 18, 2014 at 11:58 am #12648I sent you the listeners – I’ll not add the function until I hear from you.
Charlotte KittoSeptember 18, 2014 at 12:14 pm #12649Thanks Charlotte,
I can confirm there is a problem with incorrect headers being set (though I can’t replicate the 404 – instead I get a 301, but then I can’t obviously, send a valid PayPal payload 😉 ). I’m fairly certain that 1.8.3 (which I’ll release today) will fix this issue.
Stephen HarrisSeptember 18, 2014 at 12:21 pm #12650Okay – I’ll look out for it. Thanks for looking into it.
Charlotte KittoSeptember 18, 2014 at 1:01 pm #12651Just to let you know, 1.8.3 has just been released.
Stephen HarrisSeptember 18, 2014 at 4:12 pm #12653Hi Stephen,
I have just done a full upgrade to all the software on the site and I put through an order so I can confirm that the IPN issue is fixed – the IPN history says sent instead of failed or retrying.
Thanks a million

Charlotte KittoNovember 4, 2020 at 8:01 pm #38902I know this is an old post. But I really had a hard time finding what the IPN url should be that is entered in Paypal. Maybe I missed something but I didn’t see any reference to it in the plugin settings or in the documentation.
Brett HallNovember 28, 2020 at 1:12 am #38987Hi Brett,
You shouldn’t need to enter an IPN url in PayPal. If you’re having issues with payments with PayPal please follow the “Debugging PayPal IPN” at the bottom of this page: http://docs.wp-event-organiser.com/bookings/gateways/paypal/
