After a purchase has been made by the user journey you helped start, it is time to close the loop and get notified of that transaction. In this section we'll walk through **Button Webhooks** and show you how to receive order reports to an endpoint of your choice.

Button allows you to configure Webhooks so you can receive real-time updates to your system that track various user actions. To do so, you can configure and test this webhook in your [Button Dashboard](https://app.usebutton.com/webhooks). After configuration is complete, Button will send you an HTTP request when any of those events are created.

All webhooks received must be validated before acting on their contents. See [Security](https://developer.usebutton.com/guides/publishers/webhook-semantics#webhooks-security) for details.

For full source code of sample apps in Node.js, Ruby, and Python that securely receive Button Webhooks, see [here](https://github.com/button/webhook-test-apps). You can also find these in the [Example Implementation](https://developer.usebutton.com/guides/publishers/webhooks-getting-started#example-implementation) section, below.
