*  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 -X POST \
*  https://your-webapp-hostname:your-webapp-port/v1/media \
*  -H 'Authorization: Bearer your-auth-token' \ 
*  -H 'Content-Type: image/jpeg'
*  --data-binary @your-file-path

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

IF (lnSuccess <> 1) THEN
    ? "Failed to load your-file-path"
