The Fusebill API is a REST based HTTP API. It makes use of standard HTTP authentication, verbs, and error codes.

Fusebill ensures the API platform is stable and performs well under the stresses of real world use. New features are first launched against a private API resource. New API features are made public after the feature has been fully vetted in the Fusebill Admin application.
