# Check if post purchase is possible

Should be called before deciding whether to show post purchase functionality on the redirect page. This call is needed becuase it is not until the purchase is done that we can anwser this. Note that even if we anwser yes here the call to InsertItemsPostPurchase might fail regardless, since the PSP can reject the update even if it should be possible (due to risk assesments etc).

Endpoint: GET /IsPostPurchasePossbile
