I am excited to announce the availability of the Azure Pipelines app for Slack. If you use Slack, you can use the Azure Pipelines app for Slack to easily monitor the events for your pipelines. Set up and manage subscriptions for completed builds, releases, pending approvals and more from the app and get notifications for these events in your Slack channels.
We plan to continue improving the app on a regular basis. Ability to take actions from the notifications (like Approve a deployment) is next on our list. Please give the app a try and send us your feedback using the /azpipelines feedback command in the app or on the Azure DevOps feedback portal
