Permissions required for Sharepoint API calls

[CyBeRkId2002]

Hi all,

 

I am trying to create a flow that clears out a certain folder based upon a defined retention period. The files are easy and working, but folders are proving a little more problematic. They require a 'Send HTTP request to SharePoint' API call as there is no action for deleting files but it doesn't seem to be working and I get a System.UnauthorizedAccessException.

 

Does anyone know permissions required to run these commands? Is it, as I suspect, a Sharepoint Admin role? For information the user I am using does have permissions to browse and delete files within this folder on Sharepoint.
