So, I have a router with global IP address (Yeah, I know it will NOT work with the local ones, like 192.168.xx.xx) address and I've triple checked that it IS accessible from the outside.
I'm currently working in the sandbox environment.
I have all my payment options in the hidden :encrypted field (see appropriate railscast) that are being posted to PayPal. On the PayPal side everything is running pretty much smooth - I complete my payment and so on, but IPN is never called. There is simply no log-entry for my action being triggered (no errors/warnings or whatsoever), however there should be at least something.
I've tried to pass the notify_url 2 ways: 1) in the options hash in my purchase model, before being encrypted to :encrypted field; :notify_url => notify_url 2) notify_url as a separate hidden field explicitly => <%= hidden_field_tag :notify_url, notify_url %> 3) Combination of pts 1 and 2.
But it is hopeless - nothing seems to be working. :(
I have also tried to enabling the IPN in my sandbox business account settings, but that didn't do any help either.
What should I do in this situation ?
P.S I have also tried out the IPN Simulator service, and it seems to be working. What is wrong with it then ?
With trial-n-error, I've finally found a solution!
Never, I repeat, NEVER use "_cart" as a cmd for your payment if you want to use: 1) IPN, 2) PDT validation. Use "_xclick" instead!
That fixed my problem and now both of them working properly!
Hope this will be useful to someone!
