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.

Composing data in stages versus using expressions

As you progress with logic apps and build up your experience over time, you will undoubtedly get to a situation quickly where you need to look for specific records from different entities where they may be related. One such example might be the contact details for a contact, where the contact details exist not as part of the Contact record but in a linked Contact Types record. Here, the temptation is to do the following:

  1. Make your initial List records query to obtain the contact in question.
  2. Create a For each block cycling through the Value field (each record in turn).
  3. Inside the For each block, create a List records query to obtain the contact types for that person.

Figure 11.6 – First, we find the contact, and then for each one found, obtain their Contact Type records. This is inefficient

As you can see, this is one call per contact type and one call per contact, which may take several...
