GET Read bound agent configurationRead the current configuration and its agent acknowledgement. The collection interval is separate from the refresh interval of unchanged states. Custom definitions contain only declared field types and source identities, never commands or credentials.
PATCH Synchronize local changesUses stable source identities. Each changed field is applied in server acceptance order; unrelated fields and measurement history remain intact. Repeat the same operation_id and body after a lost response. Names, descriptions, activation and collection intervals synchronize. Executables and arguments remain in the locally approved policy.
