This multi-part tutorial covers the creation of a new data source extension for Power Query. The tutorial is meant to be done sequentially - each lesson builds on the connector created in previous lessons, incrementally adding new capabilities to your connector.

In this lesson, you will:

• Create a base function that calls out to a REST API using Web.Contents
• Learn how to set request headers and process a JSON response
• Use Power BI Desktop to wrangle the response into a user friend format
