To send a notification to Microsoft Teams when a flow run fails in Prefect 3.0, you can leverage Prefect's automation capabilities. Prefect 3.0 includes a new events and automation system that allows you to create event-driven workflows based on the presence or absence of specific events.
Here's a general approach you can follow:
1.
Set Up Automation Triggers: Prefect 3.0's automation system permits you to trigger actions based on specific event payloads. In this case, you would set up an automation trigger for when a flow run enters a failed state.
2.
Integrate with Teams: You would typically need to integrate with an external service to send notifications. You can use a Teams webhook for this purpose. Create a webhook in Microsoft Teams, which will give you a URL to send messages to a specific channel.
3.
Create a Notification Function: Write a Python function to send a message to your Teams webhook URL whenever the automation trigger detects a failed flow run. This function should craft an HTTP POST request containing the notification message.
Here's a brief example of how your Python function might look:
python
import requests
def send_teams_notification(webhook_url, message):
headers = {
"Content-Type": "application/json"
}
payload = {
"text": message
}
response = <http://requests.post|requests.post>(webhook_url, json=payload, headers=headers)
if response.status_code == 200:
print("Notification sent successfully.")
else:
print("Failed to send notification.")
