* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loHttp = CreateObject('Chilkat_9_5_0.Http')

* Use your previously obtained access token here:
* See the following examples for getting an access token:
*    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
*    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
*    Refresh Access Token (Azure AD v2.0 Endpoint).
*    Refresh Access Token (Azure AD Endpoint).

* (Make sure your token was obtained with the Files.ReadWrite scope.)
loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

* To create a new folder, send a POST request like this:
* POST /me/drive/items/{parent-item-id}/children

* We first need to get the item-id for the folder where the new folder will be created.
* This example will create a new folder named "abc" within /someFolder,
* so we need the item-id for /someFolder.

* Set the URL var for the next request which will create the new folder.
loHttp.SetUrlVar("parent_item_id",loJson.StringOf("id"))

* The HTTP request body should contain JSON like this:

* 	{
* 	  "name": "abc",
* 	  "folder": { }
