The Coupon API supported by Stage of Life provides access to a large number of discounts on U.S. based brands by partnering with hundreds of national companies. These coupons range anywhere from 5% to 50% off specific products, and are stored in the Stage of Life merchant offer database. The database can be accessed via a REST interface to return an XML feed that enables developers to integrate membership perks, loyalty rewards, and other discount distribution programs into a web or mobile application. The system uses smart ways of "tagging" data to increase segmentation for marketing and business goals. Discounts can be grouped into the following example categories: Entertainment Offers, Student Offers, Small Business Offers, Mobile-Friendly Offers, In-Store Offers, Family Offers, Shopping Offers, etc. All categories can be included, or the API consumer may choose to only include certain categories and only specific merchants.
