Hello Christopher, Sumit,
In case you use 3rd party lib to obtain access and refresh token, you don't
need to use verification code again (it is already used and no longer
valid).
Instead, pass the refresh token directly to the library as:
token = {
:access_token=>"AbCdEf",
:refresh_token=>"gHiJkL",
:issued_at=>(time access token issued),
:expires_in=>3600
}
adwords.authorize({:oauth2_token => token})
Note, you don't need to provide scope as it is already requested by you
with omniauth.
-Danial, AdWords API Team.
