* 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 PATCH --data-binary @JSON_FILE_NAME \
*   -H "Authorization: Bearer OAUTH2_TOKEN" \
*   -H "Content-Type: application/json" \
*   "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME"

* 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

* Adds the "Authorization: Bearer OAUTH2_TOKEN" header.
