Monitor your dag with slack alerts | Apache Airflow tutorials for beginners

[@eunheechoi3745]

I was able to create the app and install the webhook on slack. Testing the API via POSTMAN was successful. However when I run the airflow job which is failing as intended there is no slack notification sent to the channel. I see the following error - "schannel: next InitializeSecurityContext failed" any idea? and how to solve

It will notify me of all my dags if they failed or succeed ?

[@maxcoteclearning]

there are seperate callback methods for each. The one I showed is going to alert on dag failure `on_failure_callback`. You can use `on_success_callback` for alerts when dag successeds

Hi, how can I send it to multiple channels?

[@maxcoteclearning]

You'll need to create a slack webhook for each channel. Then simply sent alert on each channel (e.g. Using for loop)

Sorry for the delay. I will upload the code soon today.
