Why OData and REST API connections in Power BI? - Purpose & Use Cases

The Big Idea

What if your reports could update themselves while you focus on decisions?

The Scenario

Imagine you need to gather sales data from multiple online services every day. You open each website, copy the numbers, paste them into a spreadsheet, and try to keep track of updates manually.

The Problem

This manual method is slow and tiring. You risk making mistakes copying data, miss updates, and waste hours repeating the same boring tasks. It's hard to keep data fresh and reliable.

The Solution

Using OData and REST API connections lets Power BI automatically fetch data from online services. It updates your reports with fresh data instantly, without any manual copying or pasting.

Before vs After

Real Life Example

A marketing team connects Power BI to their social media platform's REST API to track campaign performance daily, saving hours and spotting trends faster.

Key Takeaways

Manual data collection is slow and error-prone.

OData and REST APIs automate data fetching into Power BI.

This saves time and keeps reports always up to date.
