Bases: airflow.operators.http_operator.SimpleHttpOperator

This operator 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.

  • webhook_token (str) – Slack webhook token

  • message (str) – The message you want to send on Slack

  • attachments (list) – The attachments to send on Slack. Should be a list of dictionaries representing Slack attachments.
