Not able to use api with tokens

[mikeheft]

I'm able to authorize just fine with the gem. But then I use xeroizer to hit xero's api. I'm storing the token, secret token, and oauth_verifier in a model associated with the user.
But it's not recognizing my tokens when trying to use the api. I keep getting a 401 on any request. I've tried to use the xeroizer gem's methods to exchange request token for an access token, but get a 401 there as well.
Update: I think I see what's going on finally, lol. When I access the xeroizer's client #access_token attribute, I can see the access token/secret are the same as what I'm storing from the return from this gem. Just really not sure how to address this signature issue on my end :(
