Unlike other REST APIs, these use the file ID (found in the Browser) or the UUID (found in all payloads or json representations) instead of the configuration ID.
The REST API for files follows the best practices for RESTful API design. Ensure you read the HTTP status codes and interpret them together with the responses.
For each call, you can add the following command:
-w"\n%{http_code}\n"After the username and password in order to receive more meaningful HTTP errors.
