   Bases: :class:`airflow.providers.http.hooks.http.HttpHook`

   This hook allows you to post messages to Slack using incoming webhooks.
   Takes both Slack webhook token directly and connection that has Slack webhook token.
   If both supplied, http_conn_id will be used as base_url,
   and webhook_token will be taken as endpoint, the relative path of the url.

   Each Slack webhook token can be pre-configured to use a specific channel, username and
   icon. You can override these defaults in this hook.
