Overview of this book

IBM API Connect enables organizations to drive digital innovation using its scalable and robust API management capabilities across multi-cloud and hybrid environments. With API Connect's security, flexibility, and high performance, you'll be able to meet the needs of your enterprise and clients by extending your API footprint. This book provides a complete roadmap to create, manage, govern, and publish your APIs. You'll start by learning about API Connect components, such as API managers, developer portals, gateways, and analytics subsystems, as well as the management capabilities provided by CLI commands. You’ll then develop APIs using OpenAPI and discover how you can enhance them with logic policies. The book shows you how to modernize SOAP and FHIR REST services as secure APIs with authentication, OAuth2/OpenID, and JWT, and demonstrates how API Connect provides safeguards for GraphQL APIs as well as published APIs that are easy to discover and well documented. As you advance, the book guides you in generating unit tests that supplement DevOps pipelines using Git and Jenkins for improved agility, and concludes with best practices for implementing API governance and customizing API Connect components. By the end of this book, you'll have learned how to transform your business by speeding up the time-to-market of your products and increase the ROI for your enterprise.

Introduction to API Connect pre-built transformation policies

In Chapter 4, API Creation, you were introduced to pre-configured, or built-in, policies within the policies of an API flow. Of the many to choose from, some can be used to transform your data either on the request or response flow. As you are configuring the Gateway policies of your API, you will notice that all of the pre-defined policies on the left of the page are logically grouped based on the type of functions that they perform. You will notice a Transforms grouping, which will contain five different policies that you can use within your Gateway policy flow to transform your data. Each one will perform a specific type of transformation or pertain to a specific data format to transform to and from. In addition to these five policies listed under the Transforms heading, the GatewayScript policy can also be very useful in transforming data. This policy is listed under the Policies heading. Figure 8.1 shows these different...
