Here’s how." source: "https://www.netlify.com/blog/2021/12/19/automatically-trigger-netlify-functions-on-specific-events/" last_updated: "2026-07-10T19:44:06.000Z" --- > Throughout December we’ll be [highlighting a different Netlify feature each day](https://www.netlify.com/blog/2021/12/01/highlighting-a-different-netlify-feature-each-day-in-december/). It might just be the thing you need to unlock those creative juices, and [dust off that domain](https://www.netlify.com/blog/2021/12/01/dusty-domains-your-forgotten-domains-raise-money-for-charity/?utm_campaign=devex-ph&utm_source=netlify&utm_medium=blog&utm_content=adventure-cli-dev) you registered but never deployed! Keep an eye [on the blog](https://www.netlify.com/blog/2021/12/01/highlighting-a-different-netlify-feature-each-day-in-december/?utm_campaign=featdaily21&utm_source=netlify&utm_medium=blog&utm_content=adventure-cli-dev) and on [Twitter](https://twitter.com/netlify) for each feature! Netlify Functions can be triggered via your UI with a user event like clicking a button, or visiting directly the endpoint `/.netlify/functions/` in your browser, but we’ve also made available what we call **event-driven functions**. “What is this?”, I hear you ask. There are some events happening when you use Netlify that can automatically trigger a function. For example, if you have a [Netlify Form](https://www.netlify.com/products/forms?utm_campaign=devex-cg&utm_source=netlify&utm_medium=blog&utm_content=event-drive-functions) on your site, you can trigger a function automatically when receiving a new submission, simply by naming your function file `submission-created.js`. That’s all! The events currently working with this feature are: - deploy-building - deploy-failed - deploy-locked - deploy-succeeded - deploy-unlocked - identity-login - identity-signup - identity-validate - split-test-activated - split-test-deactivated - split-test-modified - submission-created You could use them to notify co-workers when your app’s deploys are locked, or when a deploy fails, when a user signs up, and more!
