Build APIs with Remain API Studio and the RPG Generator

The RPG Generator will use boilerplate code to build the framework of your API, based on the parameter set that you specified at the API level, to enable you to simply add in your business rules or data retrieval process into a copybook that will be used at code generation time.

Using a copybook in this way allows for customization of the code to fit your exact requirements without any need to worry about breaking the API structure. Another RPG routine can be called that returns the appropriate data you want to share or use RPG or SQL to go to your database to retrieve what is required.

What Is IBM i REST API and Why Use It?

REST APIs have become the standard for system-to-system communication.
They are lightweight, scalable, and universally supported, making them ideal for connecting IBM i applications to today’s digital ecosystem.

JSON is widely accepted as the primary data format for IBM i API development. The Representational State Transfer (REST) architectural style provides interoperability between applications and services within and across organizational boundaries, enabling the flexibility that allows two applications to communicate using tools similar to those used by web browsers and web-based applications. REST APIs utilize all the HTTP actions like GET, POST, PUT, and DELETE.

They turn your IBM i into an open, connected platform, while preserving the reliability it’s known for.

Designing REST APIs with Remain API Studio

Remain API Studio is our dedicated solution for designing, managing, and generating REST APIs on IBM i. Built by IBM i specialists, it removes complexity and gives your development teams full control.

It’s important to build IBM i REST APIs according to OAS standards. Apart from adopting a worldwide standard, benefits include leveraging many commercial and open-source tools, generating documentation and code, like Java or RPG Free, and the capability to define an interface to your back end quickly.

Creating and maintaining REST APIs from scratch can be challenging.

Our IBM i developers engineered Remain API Studio to make it fast, easy, and efficient. Moreover, this tool integrates seamlessly with our ALM solutions.
