# Register New Conditional Logic

To register a new conditional logic, developers should use the following code:

```php
function register_conditional_logic( $conditional_logics ) {
    $conditional_logics->register( NewConditionalLogic::get_instance()->get_logic_data() );
}

add_action( 'yaymail_register_conditional_logics', 'register_conditional_logic' );
```

This code attaches to the `yaymail_register_conditional_logics` action hook. It is used to register new conditional logic by passing an array value of the instance class.
