How to integrate Apache Airflow with slack?

Question

could someone please give me step by step manual on how to connect Apache Airflow to Slack workspace. I created webhook to my channel and what should I do with it next ?

Answer 1

The full example with SlackWebhookOperator usage as in @kaxil answer:

def slack_failed_task(task_name):
  failed_alert = SlackWebhookOperator(
    task_id='slack_failed_alert',
    http_conn_id='slack_connection',
    webhook_token=Variable.get("slackWebhookToken", default_var=""),
    message='@here DAG Failed {}'.format(task_name),
    channel='#epm-marketing-dev',
    username='Airflow_{}'.format(ENVIRONMENT_SUFFIX),
    icon_emoji=':red_circle:',
    link_names=True,
  )
  return failed_alert.execute

task_with_failed_slack_alerts = PythonOperator(
  task_id='task0',
  python_callable=,
  on_failure_callback=slack_failed_task,
  provide_context=True,
  dag=dag)

As @Deep Nirmal Note: Make sure you have slack_connection added in your Airflow connections as
