Check if PowerApps user can access a particular SharePoint list item

Posted on by Community Power Pla... Microsoft Employee

My PowerApps is able to take the ID of the list item in the url (e.g. &ReqID=99), and display the form filled with data from the list item.

However, there are custom permissions for each list item which have been set (e.g. a requestor can only view their own request), and if i open the app with a ReqID that I do not have access to, it will show a form in "New" mode.

I am trying to show a screen that says "Access Denied" instead of showing them the blank form, and I thought of navigating to access denied screen if user does not have permission for the list item.

Is it possible to get permissions or is some other method recommended? Thanks in advance!

Hi,

I would suggest using the formula below on StartScreen:

/*This formula checks if the param ReqID exists if not it will set it as 0 and navigate to the Home screen*/ /*Then it will check if the user has access to the item if so it will redirect the user to the form screen, if not it will redirect to the access denied*/ With( {ReqID:IfError(Value(Param("ReqID")),0)}, If( ReqID=0, HomeScreen, // If it exist, if not you can remove this condition If( IsBlank(LookUp(teste,ID=ReqID)), AccessDeniedScreen, FormScreen ) ) )

I hope it helps 🙂
