I have successfully setup my Gravity Forms test WP website to work with PayPal sandbox using IPN, and PayPal correctly transfers control back to either my "success" or "canceled" URLs correctly.
Also, any subsequent display of my GF "Entries" listing correctly lists all the processed forms entries - both processed and canceled orders. However, although the detail of those processed orders shows that successful orders are correctly displaying an IPN "Payment Status" of "Approved", any orders that were canceled within PayPal (i.e., when the user clicks on SUBMIT on my form and is transferred to PayPal, and then they subsequently cancel the order from within PayPal) continue to show an IPN "Payment Status" of "Processing".
I would think that any order thus canceled would send an IPN code back to Gravity Form that it was canceled.
One other hitch: on my order form there are some order-able items that are $0.00 cost, and 99 percent of the time my users will be ordering non-zero items and simply adding these freebies to their order, but as things now stand they can create an order that only has zero-cost items.
I understand from other posts on this forum that a possible future GF feature will be to require a min amount to be passed to PayPal (which would be good for me) but in the interim my order form can pass zero-total orders to PayPal. Fortunately, though, PayPal recognizes that the order total is zero and then immediately transfers control back to my "success" URL, and a subsequent GF "Entries" list will include such orders in the listing. The one drawback is that these zero-amount orders also show up with a "Payment Status" of "Processing" (whereas in actuality they are equivalent to being "Approved" since their amount total was zero and since PayPal directed the user in those instances back to the "success" URL).
Note that these zero-amount orders - although they are apparently processed successfully by PayPal since it directs the user back to my "success" URL - do not show up in the PayPal account audit trail of processed orders (which I can sorta go along with since the order did not require any funds to complete).
To summarize my questions:
1) Should not Gravity Forms' "Entries" listing show a value of "Canceled" (rather than "Processing") for those orders that were canceled by the user within PayPal, and
2) Should not Gravity Forms' "Entries" listing show a value of "Approved" (or at least something other than "Processing") for those orders whose grand total amount was zero and, apparently, processed successfully by PayPal?
