Corticon's REST connectivity allows you to access data via REST services such that rule payloads can be enriched with REST data similar to database data. Corticon uses the Progress Data Direct Autonomous REST Connector to provide support for REST callouts. This allows you to access a REST service similar to the way you access a database. When integrated with Corticon, the Datasource can use mechanisms for smart data integration and Vocabulary mapping. Rules use these Service Callouts to retrieve data as steps in a Ruleflow, even allowing you to substitute payload attributes into REST URLs before execution.
