Hello Thomas,
You can request an authorization and get token this way (in the callback):
token = api.authorize({:oauth_request_token =>
request_token, :oauth_verification_code => params[:oauth_verifier]})
session[:token] = session[:token]
Here is how I re-create the API object from the session:
api = AdwordsApi::Api.new(config_filename)
token = session[:token]
# If we have an OAuth token in session we use the credentials from it.
if token
credentials = api.credential_handler()
credentials.set_credential(:oauth_token, token.token)
credentials.set_credential(:oauth_token_secret, token.secret)
# You may want to restore the CID as well
credentials.set_credential(:client_customer_id, selected_account)
end
Depending on how you store the session you may want to store just 2 strings
instead of the full token object.
