I am using PHP to communicate with the XML-RPC API. I have been able to successfully create and validate an invoice but I am running into a problem applying a payment to an invoice.

Does anyone know how this can be done through the API? Or have a code sample I could reference?

Thanks

Here is the code I am using. It doesnt show the actual xml-rpc calls but it shows the fields. This is using a custom handler I wrote.

echo "LOGIN<BR /><BR />";
$conn = new openerp_client($user, $password, $dbname, $server_url);

//search for company in partner model to get id
echo "SEARCH<br /><br />";
$data = array(
    0 => array('field' => 'name', 'operator' => '=', 'value' => 'Antoni\'s Company 2', 'type' => 'string')
);
$conn->search('res.partner', $data);

$partner_id = $conn->response['last_record_id'][0];

//search for company in res.comapny model to get id
echo "SEARCH<br /><br />";
$data = array(
    0 => array('field' => 'name', 'operator' => '=', 'value' => 'Antoni\'s Company 2', 'type' => 'string')
);
$conn->search('res.company', $data);

$company_id = $conn->response['last_record_id'][0];

//create the invoice
echo "INVOICE<BR /><BR />";

$data = array(
    0 => array('field' => 'partner_id', 'value' => $partner_id, 'type' => 'int'),
