Katana by NinjaMetrics is a social analytics engine that measures "social value" of how users influence each other. The Katana Analytics API allows developers to measure the value of social contributions in applications and games. This API also provides developers with detailed projections for the outcomes that matter to developers, and offers the tools to determine how effectively features facilitate engagement and social interaction. Moreover, the API documentation gives developers access to send JSON directly to Katana without using an integration library.
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.
