Hi my name is Alessio and I have a issue using the Mautic Api.  
  
here is my code

Code:

$baseUrl='https://myurl.mautic.net'; $contactApi = MauticApi::newApi("contacts", $auth, $baseUrl); $createIfNotFound = true;

```
$data = array(
    'firstname' => $emailContact,
    'email' => $emailContact,
    'tags' => $campaign
);

$contact = $contactApi->edit($idContact, $data, $createIfNotFound);
echo serialize($contact);</div>

```

  
the echo retrive this:  

Code:

a:1:{s:5:"error";a:2:{s:7:"message";s:16:"parameter\_absent";s:4:"code";i:400;}}

  
I have copy the Authentication procedure from the wiki.  

Code:

$settings = array( 'baseUrl' =\> 'https://myurl.mautic.net', 'version' =\> 'OAuth1a', 'clientKey' =\> 'myKey', 'clientSecret' =\> 'MyKey', 'callback' =\> '' ); $auth = OAuth::newAuth($settings); if ($auth-\>validateAccessToken()) { if ($auth-\>accessTokenUpdated()) { $accessTokenData = $auth-\>getAccessTokenData(); } }

  
I don't understand what's wrong with my code. What is the parameter who is absent? Could you help me?
