Customer Batch – MultiCall

Allows for faster Customer and Customer Addresses upload as well as support for custom Customer attributes.

The Customer Batch sync takes advantage of Magento’s MultiCall API.  This allows us to group our Customer API calls which will be much faster than individual API calls.  Additionally, if the CustomerAPIExtender plugin is installed, the Field dropdown list for this transaction will contain Attributes added to the Magento system on the Customer object, allowing IMan to update Customer Attributes which are not exposed to the existing Customer connector.  The fields must be added to the Customer object for them to be picked up.

The functionality should be consistent with the regular Customer connector.  Inline and child Customer Addresses will function the same as the regular versions.

If the CustomerAPIExtender extension is not installed, the additional Customer Attribute fields will not be picked up.
