Sage 300 (accpac) SDATA Create Customer

Question

I'm trying to use SDATA to create a customer but can't seem to find the proper endpoint. I've scoured the schema and have only found wkshpcustomer, but nobody seems to know what that object is.

I can, however, create an order without issue:

[POST] http://{domain}/SDataServlet/sdata/sageERP/accpac/{company}/oeorders/

<sdata:payload>
    <oeorder xmlns="schemas.sage.com/sageERP">
        <TERMS>CASH</TERMS>
        <CUSTOMER></CUSTOMER>
    </oeorder>
</sdata:payload>

When I do the same based on the following blog post (https://smist08.wordpress.com/2011/08/06/fun-with-sdata/) for creating a customer, I get the following:

<?xml version="1.0" encoding="UTF-8"?>
    <sdata:diagnoses xmlns:sdata="schemas.sage.com/.../1">
        <sdata:diagnosis>
            <sdata:severity>error</sdata:severity>
            <sdata:sdataCode>ResourceKindNotFound</sdata:sdataCode>
            <sdata:message>Resource kind: CUSTOMER cannot be found in the classMap.</sdata:message>
        </sdata:diagnosis>
    </sdata:diagnoses>

So, how do I create a customer using SDATA?
