Thank you!

Hi! Could you please point how actually is this lambda triggered once CodeDeploy deployment completed? What's the bridge setup?

You can set up an sns subscribption for code deploy events. Looks like it's triggered by those

🍺

Nice and its working perfectly, I have one issue/suggestion, slack show time in UTC for each deployment, is there any way we can change that to User machine timezone. Slack API have this ability

Thanks

Thanks

How to set microsoft team webhook in that lambda function ?
