Abstract: As part of implementing a recognition and reward system, a communications platform can employ a unique set of data structures, APIs and a rules engine that abstract the definition of rewards from the definition of rules for determining when the rewards should be made available. Accordingly, boosters may interface directly with the communications platform to offer rewards to participants but need not be aware of or involved in the process of defining the rules that will be used to distribute the rewards. Likewise, administrators may interface directly with the communications platform to define rules for making rewards available without needing to be aware of the rewards themselves. In this way, a communications platform can integrate boosters and their rewards into a recognition and rewards system without requiring tight coupling between the rules for determining when rewards should be made available and the rewards themselves.
