Shopping api issue

[iceman2785]

I have updated the shopping init file to get oauth2 credentials. The first issue is on line
request.headers['X-EBAY-API-IAF-TOKEN'] = access_token
i get error
request.headers['X-EBAY-API-IAF-TOKEN'] = access_token
NameError: name 'request' is not defined. Did you mean: 'requests'?
ok so maybe it should follow the same pattern as the other and I change i remove the request a the beggining. that seems to run a little better but then I get an error
AttributeError: 'ResponseDataObject' object has no attribute 'Ack'

im sure im just missing something simple. any help would be appriciated.
