OpenLegacy Training Materials

This repository contains hands‑on training resources used in OpenLegacy LearnUpon courses. It is intended for developers and architects learning to build APIs on mainframe and IBM i (AS/400) systems using OpenLegacy.

Repository structure

• CICS Accounts API creation flow in OL HUB/resources
  Assets for a step‑by‑step lab that shows how to create an API over CICS‑based account services using OpenLegacy Hub.

• IBMI AS400 RPC API creation flow in OL HUB/resources
  Assets for a lab that demonstrates how to expose IBM i (AS/400) programs as RPC‑style APIs in OpenLegacy Hub.

Each folder typically contains:

• Sample copybooks or program definitions
• JSON request/response examples
