Where is the 'IPN History' on the new PayPal website?

More menu -> Site map -> Transactions -> IPN History

The current PayPal for Business interface only provides a way to access IPN History if you have manually configured IPN in your PayPal account settings. In this case, you'd go to [your name] > Account Settings > Notifications > Instant Payment Notifications (click Update here), then the explanatory text there will include a link to the IPN History page.

However, that link would not appear if you have not manually configured IPN -- e.g., when your ecommerce platform automatically transmits IPN parameters to PayPal for each checkout. While you could manually enable IPN with a dummy Notification URL in order to get the IPN History link, this could result in PayPal completely disabling IPN for your PayPal account if they try sending any actual notifications to that dummy URL.

In that case, you can use this link to access IPN History directly once you're already logged into PayPal:

Note that if you have not manually configured IPN in PayPal, you will see a notice in IPN History saying, "The IPN feature is turned off. You must turn on IPN in order to create history data." That notice is irrelevant if your ecommerce platform specs IPN dynamically for each checkout; in that scenario, you can still view/search your IPN History without manually turning on IPN there.

It's still available in the same place. If you want to navigate to it

• Log in
• Profile link (white bar up top)
• IPN settings
• History link on this page

Currently it's directly at https://www.paypal.com/us/cgi-bin/webscr?cmd=_profile-ipn-notify (provided you're logged in)
