PowerApps – Update MultiPerson field in SharePoint through Power Automate

This blog will discuss how we can update a multiperson field in Sharepoint using Power Automate and input from PowerApps.


In some cases, you may have a multi-select person in PowerApps and you want to send to Power Automate for other business processes like Approval or sending data to other systems. Along with you want to create Create SP List item.

Multi-Select is always a unique process and challenging either using PowerApps or Power Automate. It gives us more challenges when we use both.
