These specifications are provided to help a developer train or learn one of the many web API IDEs available. As with any attempt at reducing a web API to a simple specification language like OpenAPI or WADL, much important information is lost. Please use these as starting points to the documentation for the Toolbox Resources, not the definitive specification. Regardless of any information contained in one of these specifications, this documentation website takes precedence.
