 Event *handlers* receive and process events. Azure Functions is one of several [Azure services that have built-in support for handling Event Grid events](../articles/event-grid/overview.md#event-handlers). Functions provides an Event Grid trigger, which invokes a function when an event is received from Event Grid. A similar output binding can be used to send events from your function to an [Event Grid custom topic](../articles/event-grid/post-to-custom-topic.md).
