Magento PayPal IPN postback failure

Already since late June, PayPal IPN suddenly didn't work properly anymore. Orders are stuck in "pending payment" status. There seems to be a problem with IPN postback:

    [postback] => (postback string)
    [postback_to] => https://www.paypal.com/cgi-bin/webscr
    [postback_result] => HTTP/1.1 307 Temporary Redirect

    [exception] => PayPal IPN postback failure. See paypal_unknown_ipn.log for details.
    [__pid] => 25117

I noted the "HTTP/1.1 307 Temporary Redirect" response. Could this indicate the problem?

Solution

  • Paypal changed their callback URI: https://developer.paypal.com/docs/classic/ipn/integration-guide/IPNImplementation/

    From now on you must use:

    https://ipnpb.paypal.com/cgi-bin/webscr
