Magento Error 623

Sometimes the configuration of a Magento store can cause problems when integrating with QuickBooks Commerce.

Problem - Error 623

Magento API integration throws an error [623] Calling parameters do not match signature when trying to set up an initial connection from QuickBooks Commerce.

Cause

This is caused by PHP installation configuration on you server.

Solution

You need to comment on "variable verification" in the Magento Zend Framework.

1. Open file lib/Zend/XmlRpc/Server.php
2. Save a backup (e.g. Server_old.php)
3. Find the following lines, and comment out

       	if (!$matched) {
               #require_once 'Zend/XmlRpc/Server/Exception.php';
               throw new Zend_XmlRpc_Server_Exception('Calling parameters do not match signature', 623);
           }
       

4. The result should look like this:

       	/*
   	if (!$matched) {
               #require_once 'Zend/XmlRpc/Server/Exception.php';
               throw new Zend_XmlRpc_Server_Exception('Calling parameters do not match signature', 623);
           }
