Demo Notifications from Webhooks

In this tutorial, you’ll learn how to create webhook subscriptions in Azure DevOps to automatically send build notifications to any HTTP endpoint. By the end, you’ll be able to trigger external workflows—such as custom dashboards, chat bots, or monitoring tools—whenever your pipeline completes.

What Is a Webhook?

A webhook is an HTTP callback that enables one application to push real‐time event data to another service. Unlike polling, where you repeatedly check for updates, webhooks deliver payloads instantly when an event occurs.

Feature	Polling	Webhook
Delivery	Client-initiated fetch	Server pushes data on events
Latency	Dependent on polling interval	Near real-time
Resource usage	Higher network load	Efficient, event-driven
Configuration	Requires scheduling logic	Simple subscription in UI or API

Scenario

Our project TestWeb hosts an ASP.NET Web API pipeline also named TestWeb. Whenever the pipeline succeeds, we want Azure DevOps to POST a JSON payload to a custom endpoint for further processing.

1. Open Service Hooks

In the lower-left, select Project Settings.
Click Service Hooks.
Choose + Create subscription.

The image shows a web interface for Azure DevOps, specifically the "Service Hooks" settings page, with a dialog box open for selecting a service to integrate with, such as "App Center."

2. Choose the Webhooks Service

Scroll through the service list and select Webhooks.
Click Next.

3. Configure the Trigger

Under Trigger on this type of event, pick Build completed.
For Project, select TestWeb.
Restrict Build status to Succeeded.
Click Next.

The image shows a web interface for configuring service hooks in a project setting, with a focus on setting a trigger for a "Build completed" event.

4. Define the Webhook Endpoint

You can deliver to any HTTP(S) URL—public or private. For this demo, we’ll use RequestBin to capture and inspect the payload.

The image shows a web interface for configuring service hooks in Azure DevOps, with a dialog box open for setting up a new service hook subscription. The dialog includes fields for URL, authentication, and other settings.

Option	Description
URL	Endpoint to receive POST requests
Accept untrusted SSL certificates	Allow self-signed or on-prem certificates (use with caution)
Authentication	Basic auth credentials (visible to project users)
HTTP Headers	Custom headers (e.g., `X-My-Header: value`)
Resource details	Level of data: None, Minimal, All
Message formats	Payload formats: Text, HTML, Markdown

Enabling Accept untrusted SSL certificates is not recommended for public endpoints.

Once you enter your RequestBin URL and settings, click Test.

curl -d '{ "name": "Yoda" }' \
     -H "Content-Type: application/json" \
     https://enkmx78wgdqmb.x.pipedream.net/

A successful test displays a green checkmark:

5. Inspect the Sample Payload

Choose All for resource details and message formats to see everything Azure DevOps sends:

{
  "root": {
    "subscriptionId": "00000000-0000-0000-0000-000000000000",
    "notificationId": 7,
    "eventType": "build.complete",
    "message": {
      "text": "Build 20150407.2 succeeded",
      "html": "Build <a href=\"https://fabrikam-fiber-inc.visualstudio.com/...\">20150407.2</a>",
      "markdown": "Build [20150407.2](https://fabrikam-fiber-inc.visualstudio.com/...)"
    },
    "resource": {
      "id": 1,
      "buildNumber": "20150407.2",
      "status": "completed",
      "result": "succeeded",
      "definition": {
        "id": 1,
        "name": "CustomerAddressModule"
      }
    }
  }
}

Click Finish to save your subscription.

Testing the Webhook in Real Time

Go to Pipelines > TestWeb.
Click Run pipeline (or Queue).
After it succeeds, refresh your RequestBin URL to view the new POST payload.

Example of a real‐time payload:

{
  "root": {
    "notificationId": 7,
    "eventType": "build_complete",
    "message": {
      "text": "Build 20150407.2 succeeded"
    },
    "resource": {
      "id": 1,
      "status": "completed",
      "result": "succeeded"
    }
  }
}

In your pipeline logs, you’ll see:

Job
  Pool: KodeKloudCustomer
  Image: windows-latest
  Agent: KodeKloudAgent1
  Started: Just now
  Duration: 22s

Editing or Creating Additional Subscriptions

Return to Project Settings > Service Hooks at any time to:

Modify existing webhooks (e.g., trigger on pull requests).
Add integrations for Microsoft Teams, Slack, Trello, and more.
Build multiple subscriptions for custom apps.

The image shows a settings page for service hooks in Azure DevOps, with a dialog box open for selecting a trigger event, such as "Pull request commented on."

Webhooks in Azure DevOps unlock powerful automation scenarios—experiment with different event types and endpoints to streamline your CI/CD workflows.
