A client for OpenEdge REST Web services can be any application that can communicate with an OpenEdge REST application on a Web sever. The only requirements are that the client is enabled to support HTTP 1.1 and that the client can parse JSON data.
If you intend to develop a client that runs on a mobile device, you will find development support in Progress Developer Studio for providing access to OpenEdge data and ABL business logic. For more information, see
Data Object Services.
