#payload(prefix = nil) ⇒ Object

Provides changeset in a format that can be thrown at an endpoint

prefix: This is needed due to inconsistencies in the EB API

Sometimes there's a prefix, sometimes there's not,
sometimes it's singular, sometimes it's plural.
Once the API gets a bit more normalized we can remove this
altogether and infer a prefix based
on the class name of the resource
