Book description

This IBM® Redbooks® publication provides insight into what application programming interfaces (APIs) are and why they are important. It also provides insight into how to use IBM API Management to create, subscribe, and connect to APIs, how to secure and test APIs, and how to gain business value from APIs.

With an API, developers can exploit the functions of existing computer programs in other applications. Today, companies are exposing APIs to allow others to consume business functions of APIs. This helps companies to extend the reach of its brand, increase customer loyalty, and innovate, and integrate more quickly with customers, business partners, and suppliers.

IBM API Management Version 2.0 is a complete on-premises solution, enabling companies to rapidly create, socialize, and manage their APIs. It is designed to help create a scalable, secure, enterprise API management solution. It provides functions and capabilities through configuration, not coding, key areas of API management including security, capabilities, caching, analytics, and community.

This book shows you how to expose and manage APIs using IBM API Management. We develop a use case example, and step through the actual implementation of the solution and usage of the APIs. We cover several known best practices and areas to consider when working with IBM API Management.

This book is written for anyone who will be working with IBM API Management for design, development, testing, deployment, administration, and maintenance of API management solutions.
