About This Course

Estimated course duration: 4 hours.

You must successfully complete IAP101 Introduction to the Itential Automation Platform before you begin this course. IAP101 is the starting point for all Itential Academy training. It describes how to use the Itential Academy online training environment, introduces Itential, and introduces the Itential Automation Platform.

Welcome to IDEV101, Itential Adapter Essentials I, part of the Itential Developer series of courses for software developers building applications and features on the Itential Automation Platform (IAP). This course is the first of two courses that teach the basic essentials to build an Itential adapter. Adapters are a part of IAP. They provide external systems integration by performing two functions: executing the external systems' APIs and abstracting those external systems through data translations, generic APIs, and light business logic.

This course and its companion Itential Adapter Essentials II course teaches learners how to build IAP adapters without any external assistance. Software developers should be familiar with the detailed, manual process to build an IAP adapter before using automation tools like Itential's Adapter Builder available from the Itential Developer Hub.

In this course, learners will study and learn a change management ticketing system in preparation for building an IAP adapter that will integrate the change management ticketing system into IAP. Learners will setup a developer's instance then learn, build, and test representative state transfer (REST) application programming interfaces (APIs) for ticket life-cycle management.

Labs are designed to be completed in sequence.

The Itential Adapter Essentials II course continues after this course with a series of incremental coding labs. In every lab learners acquire knowledge on a new principal while practicing skills taught in previous labs.

Course Goals

After completing this course, learners will be able to:

  • Describe the purpose of a change management ticketing system.
  • Locate the external system's features and documentation.
  • Practice and use the external system's features.
  • Demonstrate calling REST APIs.
  • Practice and use the external system's APIs.
