## Overview

This repository is a hands-on SAP Integration Suite portfolio: it documents API gateway artifacts and synchronous Cloud Integration flows, rather than containing a conventional application codebase. The main user paths are API consumers reaching Petstore through deployed proxies, and Postman callers receiving transformed responses from individual iFlows. The README documents these relationships and the artifacts’ behavior; no source excerpts were provided, so internal flow steps and proxy configuration details beyond those notes are not expanded.

Main entry points: [`api-management/proxies/HelloWorldAPI_Provider.zip`](https://github.com/kkthej/sap-integration-portfolio/blob/main/api-management/proxies/HelloWorldAPI_Provider.zip) (Provider-linked Proxy), [`api-management/proxies/HelloWorldAPI.zip`](https://github.com/kkthej/sap-integration-portfolio/blob/main/api-management/proxies/HelloWorldAPI.zip) (HelloWorldAPI Proxy), [`api-management/products/Product_Sample_01.md`](https://github.com/kkthej/sap-integration-portfolio/blob/main/api-management/products/Product_Sample_01.md) (Sample Product), [`cloud-integration/iflows/Postman_to_CI/src/main/resources/scenarioflows/integrationflow/Postman to CI.iflw`](https://github.com/kkthej/sap-integration-portfolio/blob/main/cloud-integration/iflows/Postman_to_CI/src/main/resources/scenarioflows/integrationflow/Postman%20to%20CI.iflw) (Postman to CI)
