CityPockets is a service that aggregates all daily deals and coupons from various deal sites, such as LivingSocial, Yelp, DailyCandy, Groupon, and BuyWithMe. CityPockets also sends email reminders when a voucher is about to expire, and they also offer a marketplace where users can sell vouchers they can't use.
The CityPockets API is coming soon. No documentation or information is available yet, but those interested should email firstname.lastname@example.org for more information.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
