Connect Your IBM i Applications To the World

Easily Build Quick & Secure REST APIs

MDRest4i makes REST APIs (web services) on IBM i easy! IBM i programmers use MDRest4i to build REST API providers and consumers quickly and easily that can integrate with your existing applications without needing additional technologies.

Employing a native ILE framework for IBM i environments, MDRest4i hides code complexities to make your developers more productive. MDRest4i’s performance-optimized code structure for parsing and translations means lightning-quick response times.

The tool suite comprises an ILE Development Framework for RPG and COBOL programs, a software development kit that will generate programs for you, and an API documentation portal. In addition, it integrates perfectly with the MDChange tool suite from Midrange Dynamics.

Create Lightning Fast APIs

Generate

MDRest4i SDK generates RPG and COBOL programs needed to get a REST API running or to call a REST API from your application regardless of the format of the payload.

Develop

You have complete control of developing your business logic, with all the power and flexibility of the RPG and COBOL languages that you are used to.

Document

MDRest4i Documenter wizards build editable OpenAPI specs to make it easy for third-party software to understand your APIs.

Layered Architecture

MDRest4i generates 80-90% of the code needed for a modern ILE RPG and COBOL API application. The result is an API layer suitable for integrating into a modern layered application.
