```

/ When it fires

Fires for each PHP object encountered when serializing WordPress hook arguments to JSON.

/ Parameters

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| $data | param | mixed | yes | Current normalized value — \`null\` initially. Return an array to replace the object. |
| $object | param | object | yes | The PHP object to normalize. |
| $class\_name | param | string | yes | Class name of the object (e.g. \`WPCF7\_Submission\`). |

```
add_filter( 'fswa_normalize_object', function ( $data, $object, $class_name ) {
    if ( $class_name !== 'My_Form_Submission' ) return $data;
    return [
        'form_id' => $object->get_form_id(),
        'fields'  => $object->get_fields(),
    ];
}, 10, 3 );
