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

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl --request POST \
*   --url https://api.frame.io/v2/assets/<ASSET_ID>/children \
*   --header 'authorization: Bearer <FRAME_IO_DEV_TOKEN>' \
*   --header 'content-type: application/json' \
*   --data '{"filesize":1570024 ,"filetype":"video/mp4","name":"rotating_earth","type":"file"}'

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

* Use this online tool to generate code from sample JSON:
* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {
*   "filesize": 1570024,
*   "filetype": "video/mp4",
*   "name": "rotating_earth",
*   "type": "file"
