Module 2 Lab 3 - Securely Deploy the S/4HANA System API

Login to the Anypoint Platform and navigate to API Manager

In API Manager we will now create an instance based on our API specification, an instance is the contract holder of our API. In API Manager, follow these steps:

The Asset type, API version, and Asset version fields should be auto-populated. Click on Next.

In the next screen, we want to copy the API ID down under API Instance ID. We need this value for the API that we created in Anypoint Studio so it can be registered and recognized by API Manager.

Switch back to Anypoint Studio to the SAP S/4HANA System API project that we created. In the application canvas, click on the Global Elements tab.

Click on Create and type in auto in the Filter field to find the API Autodiscovery element. Double-click on it to open the properties window.

In the properties window, paste your Autodiscovery API ID in the API Id field. For the Flow Name field, select the main flow (e.g. dj-sap-s4hana-sapi-main) and then click on OK to close the window.

We have now set the API ID so Anypoint API Manager will recognize our API once deployed to CloudHub. This allows API Manager to secure, manage, and monitor the API.

In order to deploy managed APIs to CloudHub we need to configure the environment in Anypoint Studio. We need to obtain client_id and client_secret from Anypoint Platform.

Navigate to the Anypoint Platform portal in your browser and open Access Management from the Hamburger Menu. In the left-hand navigation, click Business Group, select your SAP Workshop business group from root, then select Environments from upper tabs and then click on Production

Click Show to see the client_secret and then leave the window as is and navigate back to Anypoint Studio.

Switch back to Anypoint Studio and if you’re in Windows OS, click on Window > Preferences.

Expand the nodes on the left-hand navigation and go to Anypoint Studio > API Manager. In there, copy and paste the Client ID and Client Secret from Anypoint Platform into the Client Id and Client Secret fields under Environment Credentials.

Click on Validate and if it was configured successfully, you should see a green check mark.

Click Apply and Close to close the window.

We can deploy application directly using Anypoint Studio, however in real world scenarios of course the deployment process can be integrated in a CI/CD pipeline for example with Jenkins and Git

Navigate to your application in the Package Explorer and right-click on the root folder and select Anypoint Platform > Deploy to CloudHub

A new window will open up. Please select the Sandbox Environment for your deployment

Change the Application Name to something like the following:

Application Name: <username>-sap-s4hana-sapi

Navigate to the Properties tab and add these properties below.

anypoint.platform.config.analytics.agent.enabled=true

anypoint.platform.client_id=

anypoint.platform.client_secret=

In order to fill the values for anypoint.platform.client_id and anypoint.platform.client_secret, follow these steps:

Navigate to the Anypoint Platform portal in your browser and open Access Management from the Hamburger Menu. In the left-hand navigation, click Business Group, select your SAP Workshop business group from root, then select Environments from upper tabs and then click on Sandbox

From the new popup window copy Client ID and Client Secret values.

Come back to Anypoint Studio and insert these values inside anypoint.platform.client_id and anypoint.platform.client_secret fields.

Click Deploy Application

You can close the window while the application is being deployed. CloudHub will now spin up a dedicated worker instance for your application and your application will have it’s own unique URL.
