Introduction

Welcome to our comprehensive guide on using REST API in Power Query. In this blog post, we will explore how you can leverage the power of REST API to enhance your data analysis and reporting capabilities in Power BI. Whether you are a beginner or an advanced user, this guide will provide you with the necessary knowledge to effectively utilize REST API in Power Query.

What is REST API?

REST API stands for Representational State Transfer Application Programming Interface. It is a set of rules and protocols that allows different software applications to communicate with each other. REST API enables you to access and manipulate data from various sources, such as web services, databases, and external systems.

Using a REST API as a Data Source

One of the key benefits of Power Query is its ability to connect to a wide range of data sources. With the help of REST API, you can easily pull data from external systems and use it in your Power BI Desktop reports. For example, you can connect to a Blackbaud REST API to extract data from that system and incorporate it into your reports.

Power Query provides a user-friendly interface for connecting to REST APIs. You can specify the API endpoint, authentication method, and any required parameters to retrieve the desired data. Once connected, Power Query automatically retrieves the data and transforms it into a format suitable for analysis and visualization in Power BI.

In our intermittent series 'I Have the Power(query)', we delve into some of the more advanced features and functionalities of Power Query. This series provides in-depth tutorials and examples on using Power Query to call REST APIs, customizing API calls through custom columns, and leveraging parameterization for dynamic data retrieval.

Executing DAX Queries with REST API

Power Query also supports executing Data Analysis Expressions (DAX) queries against datasets using REST API. This feature allows you to perform complex calculations and aggregations on the retrieved data directly in Power Query. You can execute DAX queries against datasets residing in your workspace or other workspaces.

Power BI REST APIs for Embedded Analytics and Automation

Power BI offers a set of REST APIs specifically designed for embedded analytics and automation. These APIs provide programmatic access to various Power BI functionalities, such as dataset management, report creation, and dashboard configuration. They enable you to integrate Power BI capabilities into your own applications and automate repetitive tasks.
