SAP API management provides a very simple method for a company to manage multiple Application Programming Interfaces (APIs) under a single banner. API’s are basically bits of code that deal with interfacing different applications through procedure calls and embedded functions. These allow a regular ABAP programmer to have access to a full suite of tools in order to adapt a particular software application to his or her needs. In order for us to use these API’s however, we are going to need to set up SAP’s API management service in S/4 HANA. This tutorial is meant to walk you through the process of setting up the API Management service, and will use a SAP HANA trial which is available here:

STEP 1: Locating our Tools

Once we have successfully created our trial account and logged into the SAP HCP cockpit, we’re ready to set up the API Management Service. First we’ll select Services from the left-hand pane.

STEP 2: Navigating

The right-hand pane should have a list of services that we have available to us. In light grey should be a heading titled “Integration”. Under this heading should be a tile for SAP API Management. We’re going to click on that tile to begin the setup process.

STEP 3: Status Check and Enabling

Upon clicking the tile, a new window will fill out to show us our current status for the API Management Service. It should be saying Not Enabled currently. If this is showing as enabled, then the service is already running on our SAP install. If it shows as Not Enabled, we are going to click the Enable button once in order to alert SAP that we require this service to be running.

STEP 4: Finishing Up

Once we’ve hit the Enable button, we should have a green Enabled notification below the heading of the service name. Congratulations, we’ve successfully enabled the API Management Service for SAP!

Why should we use SAP API Management?

A lot of programmers already know how to integrate bits of code from other API’s into other unrelated code, but by far the best method of managing API’s for use with ABAP comes from SAP API Management Service. the API Management Service boasts secure governance over a number of different API’s and allows programmers to take advantage of oData, SOAP and REST while relying on a secure architecture behind it. The aim here is to have a single location that can standardize linking SAP with non-SAP applications. The API Management Service does this remarkably well.

Value and Scalability

by utilizing SAP API Management on a local server, a company can benefit from having the security and governance that the service provides while at the same time keeping their code secure from external sources. The fast deployment and integration of the system makes for a useful addition to any network that uses API’s in the local administration of their applications. Because it’s a digital asset, it doesn’t suffer from the drawbacks of hardware when it comes to scalability. if anything it can be scaled to as large a size as the company requires.

The Real Thing

While our setup situation is simulated because it utilizes a temporary trial for SAP S4 HANA, any real setup should be similar, if not exactly the same. Thanks to the degree of compatibility between individual HANA install, it doesn’t take a lot of effort to adapt any activation to any specific install. Enabling the API management Service is the first step a company can take towards securing its API assets as well as standardizing them for use across a group of coders working for the company’s benefit.
