You will learn

Create an API provider system

Prerequisites

Tutorials: Enable the SAP Integration Suite, API Management capability

Tutorials: Create an Account on the Gateway Demo System

SAP Integration Suite, API Management uses three main components to expose APIs.

The API Provider is used to abstract the connection to the backend / target system
The API Proxy is the actual API which contains the logic to connect to the target system. Here you can model the flow, add security policies, transform the incoming message or look for content injections
The API Product which bundles one or more API Proxies before they are exposed in the API Developer portal so they can be consumed by a developer

You will use SAP Integration Suite, API Management to create an API Provider. This API Provider will connect to a backend system, in your case to the SAP Gateway Developer System. In a real-life scenario the API Provider could connect to your Developer System. Once you have created and tested an API Proxy on it, you would transport the proxy to your productive system and the underlying API Provider would now point to your productive backend system.

Step 1: Learn about the API Management tools

In the next couple tutorials that are part of this series, you will take a look at the different tools that API Management provides. Get an overview of the tooling and how each component works together to help create your proxy.

Your proxy is what you expose to the outside world so they can consume your API. Review the blog to learn about the different building blocks of a proxy and how the tools SAP provided through API Management make it easier for you as a developer.

Where do you discover and consume Products that contain API Proxies?

Step 2: Open the SAP API Management Portal

Open the API Management, API Portal (you can get the URL from Integration Suite Launchpad, click on Design Develop, and Manage APIs).

Step 8: View list of services

When the URL was correct you should see a list of services available on the SAP Gateway system (this screen may look different on different browsers). If you entered your authentication details correctly, you should not be prompted for a username and password. If you are asked for a username and password, verify your credentials in the API Provider Authentication tab are your correct Gateway credentials. After 3 failed attempts, your Gateway will lock.
