API Management in SAP CPI

Hello Friends if you are looking for API Management in step by step in SAP CPI / Step by Step Procedure to Management in SAP CPI / How to Handle API in CPI in SAP / API Management Tutorial in SAP CPI then you will get answers.

API Management in SAP CPI (SAP Cloud Integration) refers to the use of SAP API Management, a capability within the SAP Integration Suite, to manage, secure, monitor, and publish APIs that are built using SAP CPI (or other backend like S/4HANA, ECC, third-party systems).

SAP CPI helps you build and expose APIs, but API Management gives you the tools to control those APIs by:

● Securing access (API Keys, OAuth, JWT, etc.)
● Monitoring traffic (usage, errors, latency)
● Limiting usage (rate limiting, quotas)
● Analyzing performance (dashboards, logs)
● Monetizing APIs (optional in advanced cases)

All the standard APIs are available in API Business Accelerator Hub/ API Business Hub

Building blocks in SAP API Management:

1. API Provider

“Where the real backend lives”

Think of this as the connection setup to your backend system, like SAP CPI, S/4HANA, or
any third-party system.

It defines where your actual service or integration is running.
You create it once and reuse it while creating multiple APIs.

Example:
create an API Provider for SAP CPI with host URL:
https://your-cpi-tenant.hana.ondemand.com

2.API Proxy

“The public-facing version of your API”

An API Proxy is a wrapper around your real API (hosted on CPI, for example). This is where
you apply policies like security, quota, or rate limiting.

External consumers never call your CPI directly — they call the API Proxy.
You can apply API key check, OAuth, etc., here.

Example:

real CPI endpoint:
https://your-cpi-tenant.com/http/customerdata

Your API Proxy (what the consumer sees):
https://api.sap.com/v1/customerdata

3.API Product

“A bundle of APIs with access rules”

An API Product is a package of one or more API Proxies that you want to offer to a consumer
(like a partner or another developer).

You define quotas, rate limits, and monetization options here.
Products are published on the Developer Portal.
Developers subscribe to a product to get an API key to access the APIs.

Example:
create an API Product called Customer Services which includes:

Customer Data API Proxy
Customer Orders API Proxy
