SlackWebhookHook(http_conn_id=None, webhook_token=None, message='', attachments=None, channel=None, username=None, icon_emoji=None, link_names=False, proxy=None, *args, **kwargs)¶
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, Slack webhook token will be used.
Each Slack webhook token can be pre-configured to use a specific channel, username and icon. You can override these defaults in this hook.
