The POS scans discount codes or QR codes presented by the customer.
Using these scanned codes, the POS requests available offers from the Storyous API.
The Storyous API forwards the request to the provider, who validates the codes and responds with applicable benefit offers.
The Storyous API then returns the validated benefit offer to the POS.
Note the codes are being scanned one by one and every addition leads to additional call to the provider, to get a fresh offer with all the inputs scanned.
