Enterprise Integration with Azure Logic Apps

By: Matthew Bennett

Overview of this book

Logic Apps are a visual flowchart-like representation of common programming actions, and are a flexible way to create logic without writing a single line of code. Enterprise Integration with Azure Logic Apps is a comprehensive introduction for anyone new to Logic Apps which will boost your learning skills and allow you to create rich, complex, structured, and reusable logic with instant results. You'll begin by discovering how to navigate the Azure portal and understand how your objects can be zoned to a specific environment by using resource groups. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will teach you the benefits and foundations of Logic App logic design. As you advance, you'll find out how to manage your Azure environment in relation to Logic Apps and how to create elegant and reliable Logic Apps. With useful and practical explanations of how to get the most out of Logic App actions and triggers, you'll be able to ensure that your Logic Apps work efficiently and provide seamless integration for real-world scenarios without having to write code. By the end of this Logic Apps book, you'll be able to create complex and powerful Logic Apps within minutes, integrating large amounts of data on demand, enhancing your systems, and linking applications to improve user experience.

Chapter 3: Referencing Data within Actions

In this chapter, we are going to look at the Declare, Instantiate, Populate (DIP) process in action and how you can make your own variables, set data, and manipulate data as the logic app run proceeds.

We will take a deeper look at JSON messages, which are the staple for sending data universally. Finally, we will also consider how data is stored and structured by applications and their underlying databases by accessing data using logical as well as physical field names.

At the end of this chapter, you will be able to use variables as well as read data stored in complex objects and pass them into an external system or application.

In this chapter, you will learn about the following:

  • Discovering how to create, initialize, populate, and use a variable
  • Discovering how to read a JSON message
  • Discovering how to reference a field using both logical and physical field names

The chapter covers the following main areas...
