Magento – How to get custom attributes from customer via SOAP API

Magento has its own soap connection. By using this connection you can new create customer. see this "http://www.magentocommerce.com/api/soap/customer/customer.create.html".Here details have been described.

There is no method implemented in the standard Magento SOAP API to get the attributes value instead of the id.

The attributes are collected in the info() function of Mage_Customer_Model_Customer_Api: lines 98-104 (as for CE 1.8.1.0)

   foreach ($this->_mapAttributes as $attributeAlias=>$attributeCode) {
       $result[$attributeAlias] = $customer->getData($attributeCode);
   }

   foreach ($this->getAllowedAttributes($customer, $attributes) as attributeCode=>$attribute) {
        $result[$attributeCode] = $customer->getData($attributeCode);
   }

So you might want to extend it there.
