Hide SharePoint List from Search & Power Platform drop-downs

Once you are using SharePoint lists as a back-ends of your Power App, you should assign correct access levels to user groups and hide SharePoint List from Site Content and Search. To achieve that, apply this simple, manually triggered flow:

Site Address – choose your SharePoint site

Method: POST

Url: /_api/web/lists/getByTitle(‘yourlistname’)

Headers:

{
    "X-HTTP-Method": "MERGE",
    "Accept": "application/json;odata=verbose",
    "Content-Type": "application/json;odata=verbose",
    "IF-MATCH": "*",
    "": ""
}

Body:

{'__metadata':
     {'type':'SP.List'},
     'Hidden':true,
     'NoCrawl':true
}

That’s it. SharePoint list now is hidden. What is important to notice, all existing flows now are still running and assigned correctly to this list.
