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

-- Implements the following CURL command:

-- curl -X GET https://graph.microsoft.com/v1.0/me/onenote/pages/{id}/content?includeIDs=true \
--   -H 'authorization: Bearer ACCESS_TOKEN'

-- Use the following online tool to generate HTTP code from a CURL command
-- Convert a cURL Command to HTTP Source Code

-- Adds the "Authorization: Bearer ACCESS_TOKEN" header.
http.auth_token = "ACCESS_TOKEN"

http:set_url_var("page_id", "0-d2298668edd74dccac7f821fa378bf64!41-3A33FCEB9B74CC15!20350")
