BadRequest when try Create folder via REST - api

Question

I've downloaded a exampled that show the files in the "Shared with everyone" folder in my OneDrive for Bussiness. It's work fine!
But, when I try to create a Folder or File (without content) like this documentation the response became with a BadRequest .
The request goes like:
string requestUrl = String.Format(CultureInfo.InvariantCulture, "{0}/files", serviceInfo.ApiEndpoint);
// Prepare the HTTP request:
using (HttpClient client = new HttpClient())
{
Func<HttpRequestMessage> requestCreator = () =>
{
HttpRequestMessage request = new HttpRequestMessage( HttpMethod.Post, requestUrl);
request.Headers.Add("Accept", "application/json;odata.metadata=full");
request.Content = new StringContent(#"{'__metadata':{'type':'MS.FileServices.Folder'},Name:'TestFolder'}");
request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
return request;
};
}
And the response is a BadRequest.
I think that my problem is in the "__metadata"'s json value. It´s is correct? Where can I find a working example implementing this operations?
Thanks in advance!
EDIT: Changing the API Endpoint from "/_api/web/getfolderbyserverrelativeurl('Documents')/files" to "_api/files" the error became to: "The property '__metadata' does not exist on type 'MS.FileServices.FileSystemItem'. Make sure to only use property names that are defined by the type."
I´m think I foward in this. But, I still continue with problems.

Answer 1

I am not sure if this can be of any help to you, as this pertains to oneDrive and not oneDrive for business.
Also the documentations are confusing :)
according to the documentation the request should be as follow:
POST https://apis.live.net/v5.0/me/skydrive
Authorization: Bearer ACCESS_TOKEN
Content-Type: application/json
{
"name": "My example folder"
}
if you can see that in the header there is authorization access token
I don't see that you sent to the server any access token. and that is why you had a bad request.

I am trying to below way to create a folder in SP and it's working for me. Hope it will work for you as well.
Create a folder using SharePoint Web API -
POST https://<Domain>.sharepoint.com/_api/web/folders
Accept: "application/json;odata=verbose"
Content-Type: "application/json"
{
"ServerRelativeUrl": "/Shared Documents/<Folder-Name>"
}
