# Log objects Log objects are useful for recording information for later reference. They have no side-effects. Carefully chosen log objects can massively simplify post-hoc debugging, especially (as we've found) when investigating merchant bug reports. A log object is a plain JSON object, having the following structure: ```json { "log": LOG_DETAILS } ``` The log details can be any JSON value. Log objects are most easily generated using the [**log tag**](/platform/liquid/tags/log.md). Log objects appear wherever task run results are visible, including the task preview and when viewing an event.
