I think you need the data
argument for your callback -- just guessing based off problems with oauth.
Looks like this problem (although I don't think you need xauth) was asked on SO:
OAuth Signature not valid error using Rauth, Python against the Vimeo API
See this ticket -- look at the source of the pull request:

Here is a thread directly dealing with Vimeo that I answered a while back that sounds like your issue:
https://plus.google.com/u/0/109199982702464952248/posts/KGMFVprjbzJ
This example uses the RAuth library
from rauth import OAuth1Service
def Authorize():
vimeo = OAuth1Service(
name='Vimeo',
consumer_key=client_id,
consumer_secret=client_secret,
request_token_url='https://vimeo.com/oauth/request_token',
authorize_url='https://vimeo.com/oauth/authorize',
access_token_url='https://vimeo.com/oauth/access_token',
base_url='http://vimeo.com/api/rest/v2',
)
try:
request_token, request_token_secret = vimeo.get_request_token(key_token_secret=access_token_secret,data={})
print(request_token)
except Exception, e:
print(e)
