How do i know if the purchase product has completed successfully. There is no method like "On Successful complete event" , only it has "Has product purchased" , but not sure how long should i wait before the purchase be completed.
My product is kind of "hints" pack where i need to add 50 hints if the purchase goes through succesffully if not 0 is added , hence the user will loose the purchase if it's completed in 2 secs as i haev 2 secs wait before i check.
Has anyone implemented this ? please advise how the behavior is ?
