SAP API Management: Discover APIs from Cloud Integration & manage them

[shruthiarjun]

Introduction

SAP API Management has been supporting discovery of Integration Flows with OData Sender adapter deployed in Cloud Platform Integration for some time now. I have written about this in one of my previous blogs. As a next step in this journey, API Management will start allowing you to discover API artifacts that are deployed in Cloud Integration which could either be OData, REST or SOAP. Creation of API artifacts is a new feature in Cloud Integration & a step by step guide for the same can be found here. The procedure to discover & auto-generate the API proxies remain the same but extended to include the additional protocols.

In this blog, we do a quick recap of the procedure to see how you could manage the APIs coming from Cloud Integration. For more detailed use case description & steps please refer to my previous blog.

Step 1: Create an API Provider

Create an abstraction to your Cloud Integration tenant by creating an API Provider of type ‘Cloud Platform Integration’. Enter the coordinates and credentials to connect to the Cloud Integration Web UI tenant. You need to do this once for every new Cloud Integration tenant.

Step 2: Discover the deployed API artifacts & auto-generate API Proxies

On clicking on Discover, you can now see API artifacts of all protocols – OData, REST & SOAP. Choose the API of interest to you, provide the credentials to securely connect to the API & optionally change the details of the API Proxy before clicking on ‘Create’.

Example of SOAP API

Example of REST API

 

Note: Auto-generation of the resources is possible for OData APIs only as of now.

Step 3: Add Policies

Navigate to the Policy designer and add the necessary policies. Deploy your changes.

Step 4: Test your API

A quick test on the managed API could be performed either using the test console or any other client.

Summary

In this blog, we saw how to discover the API artifacts deployed in Cloud Integration and auto-generate API proxies for them. This will enable the use cases of governing the API based integrations built using Cloud Integration with the strong policy configuration capabilities of API Management.
