How to send Microsoft Teams notifications on DAG's status

As stated in how to send email notifications , Airflow allows multiple ways to inform users about DAGs and tasks status.

Furthermore, it's important to understand Airflow handles these 4 status ( failure , retry , success and missed SLA ) via callbacks. You can learn more about them here

Below we explain how to use those callbacks to send Microsoft Teams notifications.

Prepare Microsoft Teams

Sending messages through Teams is done using Webhooks. These connections can be assigned to MS Teams channels.

In the channel you want to send Airflow notifications to, click the ... -> Connectors and search for Incoming Webhook .

Create channel Connector

Click Configure , give it a name, and optionally select an image to use as the sender's avatar, then click Create and you will be given a webhook URL.

Create Incoming Webhook


Store this URL in a safe place as you will need it in a subsequent step and anyone with this link can send notification to that MS Teams channel

Prepare Airflow

Create a new Integration

In Datacoves, create a new integration of type MS Teams by navigating to the Integrations admin page.

Integrations Admin

Click on the + New integration button.

Provide a name and select MS Teams .

Save Integration

Provide the required details and Save changes.


The name you specify will be used to create the Airflow-Teams connection. It will be uppercased and joined by underscores -> 'MS Teams notifications' will become MS_TEAMS_NOTIFICATIONS . You will need this name below.

Add integration to an Environment

Once the MS Teams integration is created, it needs to be associated with the Airflow service within a Datacoves environment.

Go to the Environments admin screen.

Environments admin

Select the Edit icon for the environment that has the Airflow service you want to configure and click on the Integrations tab.

Edit integrations

Click on the + Add new integration button and select the integration you created previously. In the second dropdown select Airflow as the service.

Add integration

Save changes. The Airflow service will be restarted and will include the Teams configuration required to send notifications.

Implement DAG

Once MS Teams and Airflow are configured, you can start using the integration within Airflow Callbacks to send notifications to your MS Teams channel.

MS Teams will receive a message with a 'View Log' link that users can click on and go directly to the Airflow log for the Task.

Card message

Callback Configuration

In the examples below, we will send a notification on failing tasks or when the full DAG completes successfully using our custom callbacks: inform_failure and inform_success .


In addition to inform_failure and inform_success , we support these callbacks inform_failure , inform_success , inform_retry , inform_sla_miss .

To send MS Teams notifications, in the Airflow DAG we need to import the appropriate notifier and use it with the following parameters:

  • connection_id : the name of the Datacoves Integration created above
  • message : the body of the message
  • theme_color : theme color of the MS Teams card

Python version

import datetime
from airflow.decorators import dag
from operators.datacoves.dbt import DatacovesDbtOperator
from notifiers.datacoves.ms_teams import MSTeamsNotifier

        "start_date": datetime.datetime(2023, 1, 1, 0, 0),
        "owner": "Noel Gomez",
        "email": "gomezn@example.com",
        "email_on_failure": True,
    description="Sample DAG with MS Teams notification",
    schedule_interval="0 0 1 */12 *",
    tags=["version_2", "ms_teams_notification", "blue_green"],
    on_success_callback=MSTeamsNotifier(message="DAG {{ dag.dag_id }} Succeeded"),
    on_failure_callback=MSTeamsNotifier(message="DAG {{ dag.dag_id }} Failed"),
def dbt_run():
    transform = DatacovesDbtOperator(
        task_id="transform", bash_command="dbt run -s personal_loans"

dag = yaml_teams_dag()


Quotation marks are not needed when setting the custom message. However, making use of Jinja in a YAML file requires the message to be wrapped quotations to be parsed properly. eg) "{{ dag.dag_id }} failed"
