Hi everyone! I am adding Slack notification into DAGs, I see I can customize the template file generating DAGs as updating the parameter "on_failure_callback" of DAG. But the SlackWebhookOperator needs to have "http_conn_id" connection. So how can I declare this connection? I think if I create the connection directly on Airflow UI, it will not be persistent after Meltano pipeline is redeployed.

Hi @vh! You can use environment variables: https://airflow.apache.org/docs/apache-airflow/stable/howto/connection.html#storing-a-connection-in-environment-variables
