airflow.hooks.http_hook.HttpHookThis 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.
