We ended up a virtual store for a customer from which he used the Tray store and unfortunately we are going through that unfortunate comparison between that store and ours and one of those comparisons is that he said that in the Tray shop after the payment of the product, it received a notification from the store about this payment and the payment status changed automatically. It was not on the return page. Anyone who has worked with Paypal, know if they provide some API or something of the sort to implement in our store?
