# weglot\_add\_json\_keys

With this filter you can add keys Weglot msut translate into a json content.

The filter receives an array of JSON keys (empty by default: `name`, `description` and HTML values are always translated) and must return it. The values of the keys you add are translated too.

```php
add_filter( 'weglot_add_json_keys', 'custom_weglot_add_json_keys' );
function custom_weglot_add_json_keys( $keys ) {
    $keys[] = 'message';
    return $keys;
}
```
