Having trouble with adding or removing Role Assignments on SharePoint document folders using REST API through Power Automate.

Process is to copy a Template folder with subfolders. Of which, 2 subfolders need unique permissions to prevent unwanted user access.

I believe BreakRoleInheritance is being broken properly prior Sent POST via Send HTTP request via SharePoint:

_api/web/GetFolderByServerRelativeUrl('Shared Documents/SHOW FOLDERS/2017 Budgets/01 January/SHOW20')/ListItemAllFields/breakroleinheritance(copyRoleAssignments=true,clearSubscopes=true)

Sample command sending DELETE via HTTP to remove a SP Group with ID of (6) from folder:

_api/web/GetFolderByServerRelativeUrl(‘Shared Documents/SHOW FOLDERS/2017 Budgets/01 January/SHOW20')/ListItemAllFields/roleassignments/getbyprincipalid(6)

Error output:

  "status": 400,
  "message": "The expression \"web/GetFolderByServerRelativeUrl(‘Shared Documents/SHOW FOLDERS/2017 Budgets/01 January/SHOW20')/ListItemAllFields/roleassignments/getbyprincipalid(6)\" is not valid.\r\nclientRequestId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\r\nserviceRequestId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\",
  "source": "https://xxxxxxxxx.sharepoint.com/sites/FILETRANSFER/_api/web/GetFolderByServerRelativeUrl(%E2%80%98Shared%20Documents/SHOW%20FOLDERS/2017%20Budgets/01%20January/SHOW20')/ListItemAllFields/roleassignments/getbyprincipalid(6)",

  • Fixed my issue by fixing a typo. Must have did a cut and paste badly. Nov 23, 2020 at 17:51
  • On the DELETE command, the single quote before Shared Documents was the wrong character. Nov 23, 2020 at 20:09

The following worked for me.

  1. Break Inheritance for the folder:
method: POST, content-type:application/json;odata=verbose

  1. Grant a SharePoint group with id=19 Contribution permission to the folder:
method: POST, content-type:application/json;odata=verbose


roledefid for Permission Levels are as follows:

1073741829, Full Control

1073741827, Contribute

1073741826, Read
