I was looking for which major retailers had gift card APIs.
For example Amazon has the Corporate Gift Card Program: http://www.amazon.com/gp/browse.html?node=165034011 where you can either buy a bulk amount of gift codes and then they can send you a CSV file that can be imported into a DB, or (if you spend enough) they have an API for gift codes on demand.
I was wondering if anyone can verify/deny if services exist for places like:
iTunes
Best Buy
Barnes and Noble
Starbucks
Home Depot
Target
Visa
United Artists
Or is there a site/service that has a consolidated API for working with 3rd party gift card redemption with any of the above or similar type retailers? Preferably this would be done via web services/API calls with PHP.
