# Hook
The `hook` block is a function that allows you to include a WordPress Action to change what WordPress is doing by default.
It currently accepts one parameter: the Hook name.
You can add show/hide conditions to your Hook from the Primary tab as required.
## Add
The easiest way to add a Heading is through the Cwicly [Quick Inserter](/cwicly/quick-inserter.md).
* Enable the [Quick Inserter](/cwicly/quick-inserter.md).
* Find the Quick Inserter to the left of the editor and search for Hook.
* Click to add to the page.
You can call actions created by WordPress or third-party plugins by simply entering the hook's name in the appropriate field.
* With the Hook block selected, open the Primary tab.
* Input Hook name.
Or, you can create your own action through your theme's functions.php file or a code snippet plugin.
{% code title="functions.php" %}
```php
// Your function and custom name
function cwicly_custom_action()
{
echo 'This is simply echoing simple text...';
}
// This is the action that outputs the function above into the Cwicly Hook block.
// The first parameter is the name of the action, which you will use in the Cwicly hook
// The second parameter is the name of the callback function (which is run wherever the block is placed)
// The third parameter specifies the order/priority in which the functions associated with a particular action are executed.
add_action('cwicly_hook_action', 'cwicly_custom_action', 999);
```
{% endcode %}
