Create folders in a SharePoint document library using Power Automate

Recently, I’ve seen quite a few people asking about how to create folders in SharePoint Document Libraries using Power Automate.

Create folders in a SharePoint library

In my case I have a Document Library called Documents1 and I want to create a folder called New Folder

Using the Send an HTTP request to SharePoint action it is really a 5 minute task.

Using the following REST API call I can get hold of the option to create a new folder.

_api/Web/GetFolderByServerRelativeUrl('Documents1')/Folders

Just supply the body that specifies the name of your folder.

{ '__metadata': { 'type': 'SP.Folder' }, 'ServerRelativeUrl': '/Documents1/New Folder'}

You could of course also do the same without the verbose option and nometadata instead. The body would then look something like this:

{'ServerRelativeUrl': '/Documents1/New Folder'}

Run the flow

Then when you run the flow you will see that the HTTP call is successful

And my folder is created.

Document Libraries in various Site Collections

For site collections (that aren’t the root site collection) or subsites you can use the following:

  • thanks for this Pieter. With your help i've got it working wonderfully in our environment. We have a complex file structure of folders that i was already creating (by creating a file) in order to have one folder per sales order (with these folders grouped as there's lots). Now i've added in your flow code, tweaking it to use vairables so it's easier for me to manage, so i now have numerous sub folders for each parent folder ready for the team to store all job related docs in a tidy way. This is going to be a great help. thanks !

  • Thanks Pieter

    I'm a newbie... Could you introduce me to the rights allocation for the created folders ? Let's say a main folder in the Document Library called Documents1 , with many subfolders, all accessible to Group A, one of them being accessible only to sSecurity group B ?

    Thanks,

    Gaston

    I am getting this error. I would appreciate your help.

  • Thank you for you prompt response. Here it is:

    Site Address
    Customer Bids – https://abc.sharepoint.com/sites/100010
    *Method
    POST
    *Uri
    _api/Web/GetFolderByServerRelativeUrl(‘BId%20Documents’)/Folders
    Headers

    Content-Type
    application/json; odata=verbose
    Accept
    application/json; odata=verbose
    Enter key

    Enter value

    Body
    { ‘__metadata’: { ‘type’: ‘SP.Folder’ }, ‘SpWeb.ServerRelativeUrl’: ‘/BId%20Documents/New Folder’}

    • I think that your url to the folder isn't right. it isn't a server relative url. that would be /sites/....

      • Now getting the following error. Thank you again for your help;

        "Microsoft.SharePoint.SPException"
        ]
        }
        }
        }

        • it looks like /sites/100010 is repeated twice

          also in the get folder function the parameter doesn't appear to include /sites/100010

  • Hello, I am trying to create a folder within a Document library also but is getting the following error:

    “message”: “Value cannot be null.”,
    “status”: 400,
    “source”: “https://XXX.sharepoint.com/sites/MainSite/Subsite/_api/Web/GetFolderByServerRelativeUrl(‘DocumentLibrary’)/Folders”,
    “errors”: [
    “-2147467261”,
    “System.ArgumentNullException”
    ]

    Thank you in advance!

    • inside the single quotes of the document library you need to include /sites/mainsite/subsite

        • at least in the byserverrelativeurl function as that would need to be everything after sharepoint.com

      • Tried all three combinations off adding it to the GetFolderByServerRelativeUrl and ByServerRelativeUrl, Now getting a BadGateway error.

        • I added another screenshot for site collections that aren't the root site collection

  • Hello Pieter,
    I getting this error,

    "status": 400,
    "message": "Server relative urls must start with SPWeb.ServerRelativeUrl\r\nclientRequestId: ae4e610a-a527-4136-8b88-524b59f41b3c\r\nserviceRequestId: 1fa0d69e-80cd-8000-56fe-73dfc5582595",

    appriciate your help.

  • This is interesting however I find it ridiculous that this level of effort is required to do something so common. Is makes me wonder why Microsoft does not directly support creating folders from PowerApps & Flow.

    • Don't forget that they can't cover everything. There will always be some simple things that aren't there. But imagine if you had to do all that flow does in code... it would take 10 times longer.

  • I keep on getting this error

  • Pieter, I have tried lots of combinations and am starting to go a little mad.... Any advice would be greatly received....

    • Hi,

      It looks like there is a / missing in front of sites/SurgeonCompliance in your ServerRelativeUrl

        • You would need to specify the parent folder name in GetFolderByServerRelativeUrl function and in the ServerRelativeUrl (in the Body) you will need to include the parent folder and the new folder name.
