Add A User To A SharePoint Group

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.

Step 2

Now we need to create our Microsoft Flow. Log in to Microsoft Office 365 portals. From the app launcher menu, click on flow to create a Microsoft Flow.
