[Plugin: Contact-Form-7: 3rd-Party Integration] How to interract with CF7 fields using hooks

I’ve found how to use add_filter hooks.
Here is a step by step of what I do :

1)
copy file
/wp-content/plugins/contact-form-7-3rd-party-integration/3rd-parties/listrak/functions.listrak.php
to folder
wp-content/themes/cloriatotheme/cloriatotheme/functions/
rename it like you want (i.e 3rdparty-services-filters.php)
(Note that your destination folder name depends on your theme)

2)
edit functions.php situated in your theme folder and insert a line to include your filters.php file
like this : require_once ($functions_path . ‘3rdparty-services-filters.php’);

3)
edit filters.php file to add your own filter / convertion logic

<?php

if(!class_exists(‘Cf73rdParty_ListrakCallbacks’)):

class Cf73rdParty_ListrakCallbacks {
public function __construct(){
add_filter(‘Cf73rdPartyIntegration_service_filter_post_5’, array(&$this, ‘sugar_filters’), 10, 4);
}

public function sugar_filters($values, &$service, &$cf7){
if (isset($values[“description”]))
{

$array = $values[“description”];
// Convert var if it’s an array
if (is_array($array))
$values[“description”] = implode(“, “, $array);
}

return $values;
}
}

$cf73rdpartycallback_instance = new Cf73rdParty_ListrakCallbacks();
endif; //class-exists
?>

Glad you figured out the solution. Is there anything I can do in the documentation to make stuff like this easier to find?
