User permission on Sharepoint and PA

[JackCuba]

Is there a way I can block/restrict the users from writing to a sharepoint list from Sharepoint itself? I only want them to do so through my app. 

Thank you for your help!

Hi @JackCuba ,

My thought:

1. Customize the form by PowerApps, Apply authentication mechanism to configure your SharePoint list form to be opened in view mode for some of the users.

Set App.OnSelect:

Set(CurrentUser, User())

Set SharePointIntegration.OnNew property: 

If(CurrentUser.Email in ["User1@Outlook.com", "User2@Outlook.com"], ViewForm(SharePointForm1),NewForm(SharePointForm1))

Set SharePointIntegration.OnEdit property:  

If(CurrentUser.Email in ["User1@Outlook.com", "User2@Outlook.com"], ViewForm(SharePointForm1),EditForm(SharePointForm1))

2. Disable datasheet view, Navigate to the list, Click Settings cog > list settings > advanced settings, Set 'Quick Property Editing' to No

Then user1 and user2 have no permission to write data back to the list in SharePoint site.

Hope this helps.
