Azure Pipelines with 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.

Add the Azure Pipelines app to your Slack workspace

Navigate to Azure Pipelines Slack app to install the Azure Pipelines app to your Slack workspace. Once added, you will see a welcome message from the app as below. Use the /azpipelines handle to start interacting with the app.

Connect the Azure Pipelines app to your pipelines

Once the app has been installed in your Slack workspace, you can connect the app to the pipelines you want to monitor. The app will ask you to authenticate to Azure Pipelines before running any commands.

To start monitoring a pipeline, use the following slash command inside a channel:

/azpipelines subscribe [pipeline url]

The pipeline URL can be to any page within your pipeline that has the definitionId or buildId/releaseId.

For example, for Build pipelines, use:

/azpipelines subscribe

For Release pipelines, use:

/azpipelines subscribe

The subscribe command gets you started with a few subscriptions by default. For Build pipelines, the channel is subscribed to Build completed notification, and for Release pipelines, the channel will start receiving Release deployment started, Release deployment completed and Release deployment approval pending notifications.

Manage subscriptions

To manage the subscriptions for a channel, use the following command:

/azpipelines subscriptions

This command will list all the current subscriptions for the channel and allow you to add new subscriptions.

Using filters effectively to customize subscriptions

When a user subscribes to any pipeline, a few subscriptions are created by default without any filters being applied. Often, users have the need to customize these subscriptions. For example, users may want to hear only about failed builds or get notified only when deployments are pushed to production. The Azure Pipelines app supports filters to customize what you see in your channel.

  1. Run the /azpipelines subscriptions command
  2. In the list of subscriptions, if there is a subscription that is unwanted or must be modified (Example: creating noise in the channel), select the Remove button
  3. Select the Add subscription button
  4. Select the required pipeline and the desired event
  5. Select the appropriate filters to customize your subscription

Example: Get notifications only for failed builds

Build Filters

Example: Get notifications only if the deployments are pushed to production environment

Release Filters

Approve release deployments from your channel

You can approve release deployments from within Slack without navigating to the Azure Pipelines portal. Subscribe to the Release deployment approval pending notification in Slack (which happens by default upon subscribing to any release pipeline).

Ready for approval

Whenever a deployment is pending for approval, a notification card with options to approve or reject the deployment is posted in the channel. Users can then look at the details of the deployment in the notification and take action. In the following example, the deployment was approved and the approval status is displayed on the card.


The app supports all the approval scenarios present in Azure Pipelines portal, like single approver, multiple approvers (any one user, any order, in sequence) and teams as approvers. You can approve deployments as an individual or on behalf of a team.

Commands reference

Here are all the commands supported by the Azure Pipelines app:

Slash command Functionality

Notifications in Private channels

The Azure Pipelines app can help you monitor the pipelines activity in your private channels as well. You will need to invite the bot to your private channel by using /invite @azpipelines. Post that, you can set up and manage your notifications the same way as you would for a public channel.


  • The user has to be an admin of the project containing the pipeline to set up the subscriptions
  • Notifications are currently not supported inside direct messages
  • Deployment approvals which have 'Revalidate identity of approver before completing the approval' policy applied, are not supported
  • 'Third party application access via OAuth' must be enabled to receive notifications for the organization in Azure DevOps (Organization Settings -> Security -> Policies)
