Explainer

Expression Sets serve as the calculation engine for business rules and are invoked by Integration Procedures using the set's name. Versioning allows multiple iterations of a set to coexist, where the system automatically selects the correct active version based on enablement status and ranking.

Core information

Expression Sets accept JSON input from digital processes and return JSON output to the workflow that called them.

More details and nuances

When more than one enabled version matches an Expression Set call and their StartDateTime to EndDateTime spans overlap, the version with the highest Rank is chosen.
