# Built-in formatters

Formatter classes implement logic to build messages for notifications in various formats based on [CheckResult](/reference/check-result.md).

Example usage:

<pre class="language-python"><code class="lang-python"><strong>snowkill_formatter = SlackFormatter(getenv("SNOWSIGHT_BASE_URL"))
</strong>
for r in check_results:
    response = send_slack_message(
        slack_token=getenv("SLACK_TOKEN"),
        slack_channel=getenv("SLACK_CHANNEL"),
        message_blocks=snowkill_formatter.format(r),
    )
</code></pre>

### Common arguments

* **snowsight\_base\_url** (str) - should be copy-pasted from browser window. It usually consists of `http://app.snowflake.com/`, followed by organisation name and account name. But it might be different for old accounts and accounts with Private Link.\

### Usage notes

* Formatters return list of message blocks instead of one large strings. This approach helps you to extend and make minor adjustments to message format without implementing your own custom formatter.
