I'm using:
- devise
- omniauth
- omniauth-google-oauth2
- google-adwords-api
I get the token from the oauth callback:
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def google_oauth2
session[:token] = request.env["omniauth.auth"].credentials
...
end
end
I'm following the example of adwords on rails for instantiate the API
def adwords_api
@api ||= create_adwords_api
end
def create_adwords_api
api = AdwordsApi::Api.new Rails.application.config_for(:adwords)
token = session[:token]
if token
credentials = api.credential_handler
credentials.set_credential :oauth2_token, token
credentials.set_credential :client_customer_id, current_user.id
end
api
end
But when I try to fetch the campaigns, this error appears:
[AuthenticationError.OAUTH_TOKEN_HEADER_INVALID @ ; trigger:'<null>'
and based on the log, this is the url of the request:
[2015-01-09T10:12:44.237172 #6481] DEBUG -- : SOAP request: https://adwords.google.com/api/adwords/cm/v201409/CampaignService
What causes this error to occur? and how to fix it?
