I'm trying to grant access to a folder in SP using the HTTP card, keep getting string is not correct format, can anyone see the issue in this string?
 
_api/web/lists/getbytitle('<LibraryName>')/items('<Folder1>/<Folder2>')/roleassignments/addroleassignment(principalid=20,roleDefId=1073741830)

    It's been a few years since I've tried, but I was never successful at ever setting a folder permission. My questions are probably still floating around unanswered.

    The items() method part of your id is using '<Folder1/<Folder2>'. However this method expects an itemid (which is a number).
     
    Can you lookup the itemid of the folder2 and try again?

    For anyone with this issue in the future, the below will work.
     
    _api/web/GetFolderByServerRelativeUrl('<libraryName/Folder1/Folder2>')/ListItemAllFields/roleassignments/addroleassignment(principalid=<IDofGroup>,roledefid=1073741826)

    To clarify, setting permission to a folder in a Document Library is simple. Setting them for a folder inside a regular list is impossible.
