In this how-to guide, I’ll show you how to use the latest version of MuleSoft’s Anypoint Connector for IBM i (AS400) to accelerate wrapping business logic program into a REST API without any IBM i tools or development required. Once the IBM i (AS400) API is developed, it can be plugged into Anypoint Platform for added security, governance, and operational insight.
