ckeck if special user has access to a document in SPO

[iw]

hi to all,
i have a flow triggered from a powerapp and a user email address comes from the app.

In the flow i try to check if the user (from email address) has access to a special document in a document library.

If not the flow should not give back the content of the document.

How can i do the access check?

regards

Hi @iw 

Use the REST API method HTTP Get method getusereffectivepermissions(@user)?@user='<user login name>' to determine user permissions.

Look section GetUserEffectivePermissions method

Hi @iw 

Since your PowerApp is calling Flow it will do so in the context of the current logged in user

If you try and query that special document library item for the current user it will either return no results or exception

For no results you can check the length of the result set, if 0 then user does not have access

If exception for file not found =, you can configure run after step and return empty content
