# Automation

This topic describes some basic automations. For more information, see [Automations](/docs/automations/automation).

## Email notifications

Use email notifications to notify your team, or your customers, when specific event occurs. Rebilly uses a liquid template engine to render the email by replacing merge tags (placeholders) with actual values related to the event. For more information, see [Email notifications](/docs/automations/email-notifications).

## Webhook notifications

Use webhooks to notify your systems when certain events occur, and to collect information about the events. For more information, see [Webhooks](/docs/dev-docs/webhooks-configuration).

## Events

An event occurs when specific object changes state. An action is an operation that executes when an event occurs.

Use events to:

- Share data with third-party systems.
- Automate certain actions.
- Send email notifications.
- Send webhook notifications.
