Post messages to Slack in response to events in your Azure DevOps organization, such as completed builds, code changes, pull requests, releases, work items changes, and more.

Note

For Azure DevOps Services, we recommend you use the following suite of apps which offer rich features, to integrate with Slack.

Azure Boards app for Slack

Azure Boards app for Slack helps to easily create and monitor work items from your Slack channels. Users can create work items using a slash command, or use message actions to convert conversations in the channel into work items. Users can also set up and manage subscriptions to get notifications in their channel whenever work items are created or updated.

Azure Pipelines app for Slack

Azure Pipelines app for Slack helps to easily monitor the events in your pipelines. Users can set up and manage subscriptions for completed builds, releases, pending approvals and more from the app and get notifications for these events in their channels. Users can also approve release deployments from their channels.

Azure Repos app for Slack

Azure Repos app for Slack helps to easily monitor the events in your repositories. Users can set up and manage subscriptions for code commits, PR creation and PR updates and more from the app and get notifications for these events in their channels.

Create a custom app in Slack

Refer to the Slack documentation, Sending messages using Incoming Webhooks to understand the process of using Web Hooks to push information to a Slack channel.
Create a new Slack app
Activate incoming Web Hook and add a new Web Hook to the desired workspace
Select the channel for which Web Hook must be created
Copy the Web Hook URL and go to Azure DevOps

Create a service hook subscription in your organization

Go to your project Service Hooks page:

https://{orgName}/{project_name}/_settings/serviceHooks

Select Create Subscription.
Choose the types of events you want to appear in your Slack channel.

You can filter each of the triggers in specific ways. For example, the pull request created trigger can be filtered on the repository in which the pull request occurs, the target branch it applies to, and the team members that are required or invited to review the request.
Paste the Web Hook URL from the Slack integration that you created and select Finish.
Now, when the event you configured occurs in your project, a notification appears in your team's Slack channel.

Go to your project Service Hooks page:

https://dev.azure.com/{orgName}/{project_name}/_apps/hub/ms.vss-servicehooks-web.manageServiceHooks-project

Select Create Subscription.
Choose the types of events you want to appear in your Slack channel.

You can filter each of the triggers in specific ways. For example, the pull request created trigger can be filtered on the repository in which the pull request occurs, the target branch it applies to, and the team members that are required or invited to review the request.
Paste the Web Hook URL from the Slack integration that you created and select Finish.

Q & A

Q: Why don't I have the pull request events as an option when I configure my trigger?

A: Pull requests are only available with projects that use Git. If your project uses TFVC, pull event triggers aren't available, and your code event is called "Code checked in" instead of "Code pushed".

Q: How can I get multiple events to show up in my Slack channel?

A: Create a new subscription for each type of event you want. For example, if you want to see build failures and new work items in your Slack channel, create two additional subscriptions.
