(AutoIt) List Files and Folders in a SharePoint Documents Library

See more SharePoint Examples

This example shows how to use Chilkat's HttpCurl class to list the files and folders in the root of a SharePoint Documents document library. In Microsoft Graph, a SharePoint document library is represented as a drive. The example demonstrates how HttpCurl automatically resolves the SharePoint site name to a site ID, finds the drive ID for the Documents library, and then retrieves the children of the library's root folder.

Note: This example requires Chilkat v11.0.0 or greater.

; This example lists the files and folders in the root of the SharePoint
; Documents document library.
; 
; In Microsoft Graph terminology, a SharePoint document library is represented
; as a "drive".  The default document library is commonly named "Documents".
; This example shows how HttpCurl can automatically resolve the needed values:
; 
;   site_name  ->  site_id
;   site_id    ->  document_library_id
; 
; After those values are known, the final request lists the children of the
; root folder in the Documents document library.
