It seems like you’re inquiring about Azure DevOps webhooks. Webhooks are a way for an app to provide applications with real-time information, allowing them to integrate with other parts of the system easily. In Azure DevOps, webhooks are used to connect with different parts of the Azure DevOps ecosystem, or even with other third-party applications.

Here’s an outline of what you need to know about Azure DevOps webhooks:

1. Creating a Webhook: You can create a webhook in Azure DevOps by navigating to the appropriate project, then going to the Service Hooks page and creating a new subscription.

2. Supported Events: Azure DevOps supports various events like code pushed, pull request created, work item updated, etc. You can set the webhook to trigger on any of these events.

3. Payload: When the event occurs, Azure DevOps sends a POST request with a payload containing information about the event to the URL you’ve specified.

4. Security: You can secure the webhooks using a secret token that ensures that the payload is sent from Azure DevOps.

5. Customization: You can customize the payload and filter events so that the webhook only triggers under specific conditions.

6. Monitoring and Debugging: Azure DevOps offers monitoring tools to check the delivery status of events. It helps in debugging if there is a failure in the delivery.

7. Integration with Third-Party Tools: Azure DevOps webhooks can integrate with numerous third-party tools such as Slack, Jenkins, etc. This integration helps in creating powerful, automated workflows.

Here’s a simple example of creating a webhook to send notifications to Slack:

• Navigate to the Service Hooks page in Azure DevOps.
• Click on ‘+ Create Subscription’.
• Select ‘Slack’ from the list of services.
• Choose the event you want to trigger on (e.g., ‘Build completed’).
• Fill in the required details, including the Slack webhook URL.
• Test the webhook to make sure it’s working.

Please make sure to follow best practices in terms of security and compliance with your organization’s policies. If you have any specific questions or need guidance for a particular scenario, feel free to ask!
