Paypal IPN Failing – email from Paypal

Hi EE. We’ve received several emails from Paypal recently saying that our Paypal IPNs are failing. I searched online and through your forums, but much of the info I found is older, and also I’m a bit confused between Paypal Pro, Standard, Express, etc. We currently have Paypal Pro integrated with EE.

I wanted to see if you have some insight regarding this as I feel I could troubleshoot this forever. We do have a decent amount of Abandoned Registrations, but we also have plenty of Successful Registrations, and all my tests have also worked.

Below is the email we’ve received from Paypal:

Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.

Thank you for your prompt attention to this issue.

Hi there,

PayPal Pro does not use IPN’s and the URL you’ve mentioned above using gf_paypal_ipn wouldn’t be from Event Espresso.

gf_ suggest gravity forms so are you that to collect payment using PayPal Standard? If so that’s what is causing the above.

Clicking on the link shows page not found so I’m guessing this is from a previous install/form that is no longer used?

Hi Tony thanks for the insight. We are using Paypal Standard to collect, and we are using Gravity Forms on the site, but Gravity Forms is not being used to collect any payment, it’s only being used for Contact forms.

Do you think switching over to Paypal Pro would solve this issue?

Thanks again.

Do you think switching over to Paypal Pro would solve this issue?

I don’t advise switching to PayPal Pro, it requires a much higher level of PCI Compliance.

I’d recommend switching to PayPal Express, it uses the same account type as standard but doesn’t use IPN’s:

(We deprecated PayPal standard a while ago due to how unreliable IPN’s can be so I recommend the switch above either way).

However, as mentioned the URL you’re getting the email for isn’t from Event Espresso so I can’t say if it’ll stop the emails.
