Bad Request Creating Folder In SharePoint

[pcmarley]

Hello,

I'm trying to create a folder in SharePoint:

folder_url = 'https://<site url>/_api/web/folders'
headers = {
    'Authorization': 'Bearer {}'.format(my_access_token), 
    'Accept': 'application/json; odata=verbose',
    'Content-Type': 'application/json; odata=verbose',
}
req = {
        '__metadata': {
            'type': 'SP.Folder'
         },
         'ServerRelativeUrl': 'Shared Documents/mytestfolder'
}

r = requests.post(folder_url, data=req, headers=headers)
r.raise_for_status()

The return is always:

## 400 Client Error: Bad Request for URL: https://<site url>/_api/web/folders

Is there something I've missed? 

Thanks.

Can you try inserting a '/' in the front of your 'ServerRelativeUrl' parameter? i.e.

'ServerRelativeUrl': '/Shared Documents/mytestfolder'

Provide ServerRelativeUrl in this format: "/sites/siteName/Shared Documents/mytestfolder".

Here are some of working examples you can refer to create a folder in SharePoint:

Creating folder with payload:

//HTML - function calling
<button type="button" onclick="createFolderWithPayload()"> Add Folder with Payload</button>

//JS - function to create a folder
function createFolderWithPayload() {
	var folderEndpoint = _spPageContextInfo.webAbsoluteUrl + "/_api/web/folders";
	var folderPayload = {
		"__metadata": {
			"type": "SP.Folder"
		},
		"ServerRelativeUrl": "/sites/SPConnect/Shared Documents/folder1"
	};
	
	$.ajax({
		url: folderEndpoint,
		type: "POST",
		data: JSON.stringify(folderPayload),
		headers: {
			"X-RequestDigest": $("#__REQUESTDIGEST").val(),
			"accept": "application/json;odata=verbose",
			"content-type": "application/json;odata=verbose"
		},
		success: function (data) {
			console.log("Folder created successfully");
		},
		error: function (error) {
			console.log(error);
		}
	});
}

 Creating folder without payload:

//HTML - function calling
<button type="button" onclick="createFolder('/sites/SPConnect/Shared Documents', 'folder2')"> Add Folder </button>

//JS - function to create a folder
function createFolder(folderPath, newFolderName) {
	var folderEndpoint = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getfolderbyserverrelativeurl('" + folderPath + "')/folders/add(url=\'" + newFolderName + "\')";

	$.ajax({
		url: folderEndpoint,
		type: "POST",
		headers: {
			"X-RequestDigest": $("#__REQUESTDIGEST").val(),
			"accept": "application/json;odata=verbose",
			"content-type": "application/json;odata=verbose"
		},
		success: function (data) {
			console.log("Folder created successfully");
		},
		error: function (error) {
			console.log(error);
		}
	});
}
