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

Chilkat.Http http = new Chilkat.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.)

// 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.
