Introduction

In this blog, we will see how to add a user to a SharePoint group when an item is created or modified using Power Automate or Microsoft Flow. We need to follow the below steps to add a user to a SharePoint group.

Step 1

I have created a custom list with a user field. When I update an item with a user value, that particular user will be added to our group.
