Add user group permissions to a file in a sharepoint library - send an http request to sharepoint

[PipManifold]

Hi there,

I’m trying to add access to a user group using Flow.

I’m building a minutes repository and I’ve created a PowerApp which the different disciplines in our college can add the minutes to it using.

On the repository SharePoint I have created a user group for each discipline and I want Flow to give the correct group access. From my reading, you use a send HTTP request to Sharepoint to get the group and as it identifies using a string I’m getting PowerApps to look up the group name.

Then you initialize the variable using this function: body(‘Send_an_HTTP_request_to_-SharePoint’)[‘d’][‘id’]

Then you use a second Send an HTTP request to SharePoint but my flow is failing to add the user group.

I think it might be because my URI expression is for lists and I want to add permission to a file in a library.

Any help would be greatly appreciated

Hi @PipManifold :
If you want to assigning permission for folder ,maybe you could try:

https://{site Url}/_api/web/GetFolderByServerRelativeUrl(‘Lists/{DocLibName }/{folder url}’)/ListItemAllFields/roleassignments/addroleassignment(principalid={User or group id},roleDefId={Role definition id})

I think this link may help you a lot:
SharePoint REST API URL for accessing List items,documents,assign permission in list, document libra...
