This document discusses agile integration and APIs. It covers various use cases for events, data, and enterprise integration patterns. It also discusses API management foundations like controlling access, visibility, and flexibility. The remainder of the document focuses on the API lifecycle from design to implementation to operation. It provides examples of tools that can be used for API design, implementation, testing, deployment and management. Finally, it outlines hands-on tasks for setting up a database, designing an API, implementing and publishing an integration, testing, deploying, securing and consuming an API.

5. API Management Foundations
CONTROL
❏ Securing APIs
❏ Traffic flow control via policy
❏ Policy extensibility
VISIBILITY
❏ Developer onboarding and engagement
❏ Traffic and policy alerts
❏ Use analytics to understand how APIs are tracking
against business objectives
FLEXIBILITY
❏ Centralized management and distributed enforcement
❏ API management architecture must span multiple
environments

8. DESIGN: APICURIO

(API contract
specification)
» Purpose: create an API contract covering technical and syntactic
definition of a future API. Contract provides a clear description of API
methods and custom resources that are manipulated.
» Tooling: Apicurio allows you to design an API contract the easy way !
Provides an online WYSIWYG editor with compliance check on OpenAPI
Spec.
» Output: Specific OpenAPI contract saved into a Git repository (online
version is using GitHub).
» Enable: API Designer to distribute clear and concise specification of API
to development and consumers.
