' This example assumes the Chilkat API to have been previously unlocked.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.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
