What are people saying About REST4i?

REST4i is one of the slickest tools I have seen on the IBM i in many years.

I've been an RPG programmer for a long time, and it (REST4i) taps into the power of the IBM i like no other tool I've seen.

REST4i has worked even better than we could have hoped for. Our API strategy has leaped years ahead.

We had our first REST service running on our IBM i within an hour of downloading REST4i.

Different Ways to Build API's with REST4i

There are various tools and approaches for building RPG REST API's and Consumers over the LXR iCore Framework.

LXR RDi is a RDi/Eclipse Plugin supplied by Remain Software, which generates REST API's & integrates SCM workflow with TDOMS

LXR iCoreprovides templates and examples in RPGLE, for each typical use case.

LXR Accelerator generates SWAGGER specs & API RPG code stubs automatically, with DB2 field mapping & SQL IO built-in.

LXR Accelerator documents REST APIs from RPG API code & catalogues these in a developer portal.

API Quick Start

A Quick Start Service to Learn how to build, secure and deploy a REST API

End-to-End API Pilot with Quick Start

Digital integration potentially spans many architectures, tools, methodologies, and standards. Many of these are new and constantly evolving.

Making the right decisions and selections in managing, developing and deploying API's is critical for security, flexibility and competitiveness.

An API project typically involves business stakeholders, infrastructure and development teams.

Our experienced consultants can bring these technologies and teams together in a two-week Agile sprint, using a focused business deliverable to build a functional REST API Pilot.

The key API areas covered are:

  • API Management
  • API Development
  • API Deployment
