Summary

While creating a PowerApps app, we needed to add a button that would be visible only for a particular set of users who were present in a specific group in SharePoint. This was accomplished with the help of Flow.  

We would check with the help of Flow that the user that is trying to access the App, is present in the group or not. If yes, the button is available and if not, the button won’t be. 

The approach goes like, 

Step-1

Create a SharePoint Security Group and add the users who would have the access to the button in PowerApps App.

And enable the access to view the members of the Group to Everyone, so that when the user tries to login, not all users would be in the group.

Step-2

Creating the Flow 

  • Create the Flow, with the trigger PowerApps of PowerApps connector.

  • Add an action, Initialize variable of Variables connector. Set the name as isAdministrator to store a Boolean value.

  • Add another Initialize variable of Variables connector. Set the name as UserGroupInfo to store a Boolean value. 
  • Add an action, Send an HTTP request to SharePoint of SharePoint connector.  
Site Address – Select the site address where the security group is created 

Method – GET 

Uri – api/web/sitegroups/getByName(‘SharePoint Group’)/Users?$filter=Email eq ‘’ 

Replace the SharePoint Group with the name of the group created in Step-1. Here I had created the group ‘Line Manager’.  

Put the cursor pointer in between the single quotes and select the option from PowerApps, SendanHTTPrequesttoSharePoint_Uri from dynamic content window.

  • Add an action, Set Variable of Variable connector. Select the variable UserGroupInfo in Name and value as Body from Send an HTTP request to SharePoint from dynamic content.

  • Add an action, Condition of Control Connector. Set the conditional value as variable UserGroupInfo and select the condition is not equal to and in value  to be compared as ‘[]’. 

     Inside the if yes and if no options, 

 For the option if yes, add an action Set Variable of Variable connector. Select the variable  isAdministrator and set the value as true, 

         For option if no, add an action Set Variable of Variable connector. Select the variable isAdministrator and set the value as false.

  • Add an action, Respond to PowerApps of PowerApps connector. Select the text option for the output. Set the variable as isAdminUser and the value as isAdministrator from the Dynamic content.

The final look of the flow would be like this:

Step-3

Implementing the Flow with PowerApps App 

After the Flow is ready, lets configure the same with the App to test it. 

On the first screen that would be visible when you run the App, on its OnVisible Property, set the variables as below:

First, we take the variable isAdmin and set it as false.  

Secondly, we would check with the flow to set the variable UserGroupInfo as the flow’s outcome.   

On the button’s visible property, set it as If(isAdmin, true). SO that if the user is in the SharePoint Group the button would be visible else it would not. 

So when a user is inside the SharePoint Group, the screen would display the button:

And when the user is not, we display:
