## Get notified when your Workers builds succeed or fail

Jan 09, 2026 

[ Workers ](https://developers.cloudflare.com/workers/)[ Queues ](https://developers.cloudflare.com/queues/) 

You can now receive notifications when your Workers' builds start, succeed, fail, or get cancelled using [Event Subscriptions](https://developers.cloudflare.com/queues/event-subscriptions/).

[Workers Builds](https://developers.cloudflare.com/workers/ci-cd/builds/) publishes events to a [Queue](https://developers.cloudflare.com/queues/) that your Worker can read messages from, and then send notifications wherever you need — Slack, Discord, email, or any webhook endpoint.

You can deploy [this Worker ↗](https://github.com/cloudflare/templates/tree/main/workers-builds-notifications-template) to your own Cloudflare account to send build notifications to Slack:

[![Deploy to Cloudflare](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/templates/tree/main/workers-builds-notifications-template)

The template includes:

* Build status with Preview/Live URLs for successful deployments
* Inline error messages for failed builds
* Branch, commit hash, and author name
