I understand that, by default, Magento doesn't expose the vat_id field via SOAP. The accepted answer there is to edit the core/add a module. Unfortunately, I don't have such luxury because I don't have the filesystem access to Magento: I have just the basic SOAP access and I cannot do any modification.
So: how do I retrive the vat_id via SOAP from a Magento ver. 1.9.4.2?
This is what I've tried so far:
$result = $proxy->salesOrderInfo($sessionId, '200000006');
$customer = $proxy->customerCustomerInfo($sessionId, '765');
$addresses = = $proxy->customerAddressList($sessionId, '765');
foreach $addresses:
$proxy->customerAddressList($sessionId, '211');
Unfortunately, the vat_id is nowhere to be seen.
What can I do?
