This session was presented at BLUEPRINT 4D 2026.
King County sought to modernize its legacy “one size fits all” web services by transitioning from SOAP/XML-based component interfaces to RESTful services with the Application Services Framework (ASF). This allowed us to streamline and automate deployments to our API management provider. As part of this transition, we adopted the OpenAPI specification to standardize our API definitions. In this session, we’ll explore our use of ASF, the differences between document-centric and schema-driven parameters, and the implications of Design First versus Code First methodologies. Some of the shortcomings of ASF will also be discussed.
