The OpenEdge.Net library provides classes and interfaces that enable you to make HTTP requests and process HTTP responses from within ABL code. It is included in the PROPATH by default when you create a new OpenEdge project in Progress Developer Studio for OpenEdge. You can also find it in $DLC/tty/netlib (Unix and Windows) and $DLC/gui/netlib (Windows only).

The OpenEdge.Messaging library is a platform-independent API for using event streaming platforms such as Kafka. You can find it in $DLC/tty/messaging/ (Unix and Windows) and $DLC/gui/messaging/ (Windows only).
