Experience
Bonnus API
http://www.bonnus.meIt minimizes the development effort from the client-side and provides all the rewards functionality in a web application. The API logic decides which reward or gift card is better for the user, depending on several variables, including age, gender, geo-localization, or other preferences. The client only needs to initialize the user in the API and decide when he should be rewarded, and then the API chooses if the user wins o not. The API includes other functionality like sending the reward by email, gift card links, or referral programs.
The client can save more than 60% on the campaign budget when he uses the API and its functionality.
