eBay Trading SOAP API — invalid AppId?

Question

I'm trying to get my first call through to the eBay Sandbox using the SOAP API

I keep getting an Invalid AppId response. I quadruple checked that I do in fact have the proper AppIp for the Sandbox environment. eBay documentation is fairly unhelpful.

I'm using SUDS and Python 2.7 to make the calls.
