curl    -X PUT -D -                                                 \

As you can tell, my only pre-existing variables are USER, API_KEY, CONTAINER, SOURCE and DESTINATION. (SOURCE and DESTINATION would be something like my_old_file.zip and my_new_file.zip, respectively).

The variables AUTH_TOKEN and STORAGE_URL come from your authentication request, which is crucial for this to work :)
