PayPal IPN issue with Registration Payments on Event Espresso 4.9.65.decaf

Hi,

You can actually disable the IPN setting in your PayPal account, because the PayPal Express gateway does not use IPNs.

To disable the IPN setting, you follow these steps:
1) Log in to your PayPal.com account.
2) Look for Profile (gear icon) on the top of your screen and click on it. Then click on Profile and Settings.
3) Click on My selling tools. Then click on the Update link for Instant Payment Notifications.
4) The next screen will include an option to disable the IPN, here’s what my PayPal account settings for IPN look like:

Thanks. Our setup is a tad bit complicated. We have this plugin on the main site (of a multisite). No other payment plugins are present on the main site. We have a sub site (using subfolder structure, not sub-domain structure) that is a store site using WooCommerce, and I have IPN enabled on that site due to having read about use of IPN with WooCommerce.

We’re getting IPN error notices on event registrations on the main site, and yet disabling IPN on PayPal would presumably impact the sub site, potentially detrimentally.

I sure am open to advise and I appreciate the time you already took to respond.

For what it’s worth, I think our WooCommerce setup is also using PayPal Express – although I cannot remember for certain if it is using PayPal Express *exclusively*.

Just wanted to point out that the URL you shared is broken (page can’t be found/404):

Dear Seth:

As I said in my original post:

The page in question is not “inputted” by us at PayPal or on our WordPress site, so I’m thinking it must be coming from the Event Espresso plugin’s code.

The fact that page cannot be found, is not anything I can fix by editing a URL I did not create (anywhere, either on PayPal or in our site), nor is it something I can fix by simply creating a page. The page would need to have special functions/code for corresponding with PayPal’s IPN messages.

One part of this I thought would be more obvious, but perhaps needs to be asked straight out, is:

Is there somewhere inside the Event Espresso 4 plugin where the user has control over IPN (on or off) or over the URL for IPN if it cannot be turned off in the plugin?

That’s really what I was driving at when I mentioned the IPN messages are being sent to a page at a URL we did not input anywhere.

I hope that helps someone help us! LOL.

Thanks for being so kind and thanks again for such a great plugin.

Also, to add more info for better clarity:

Where in our PayPal setup we have IPN enabled, the URL we have entered there is *not* the above URL that is throwing errors whenever a site user pays for an event registration via this plugin.

Is there somewhere inside the Event Espresso 4 plugin where the user has control over IPN (on or off) or over the URL for IPN if it cannot be turned off in the plugin?

No.

I followed up with a developer on this and they mentioned we don’t listen for any callback from PayPal when using PayPal Express.

Thanks!

I’m at a loss for where PayPal is conjuring that URL from. Maybe it’s some kind of default URL they look to, based on the vendor’s domain.

I appreciate the help!
