Back to Index

Deletes a fie (also known as an object) from a Google Cloud Storage bucket. The name of the bucket is specified in the URL's path. This example deletes the "starfish.jpg" object from the "chilkat-test" bucket. A successful DELETE is indicated by a 204 response status code with an empty response body.
