Payables Invoice REST web service security

Summary

Privilege to create invoice with REST web service

Content

I'm trying to create a payables invoice using a REST web service and getting a 403 Forbidden message.  I have assigned the appropriate Accounts Payable Manager role, data access to business unit, and created a custom role with the "Create Payables Invoice by Web Service" privilege then assigned to my user.

Is the "Create Payables Invoice by Web Service" privilege only applicable to SOAP web services?  If so, what is the privilege required for creating with REST?
