Autheticate without browser

[rsinghtr...@gmail.com]

Hi,

I am using DCM/DFA Reporting API , and using these python samples https://github.com/googleads/googleads-dfa-reporting-samples/tree/master/python/v2.6 . Problem is , authentication on these happens using a browser , however in production environment we cannot install a browser and want a ETL tool to call these python scripts . Thus neither we can authenticate online (using browser ) nor offline ( by providing authentication code in command prompt ) .

Is there a way which we can follow to pre-authenticate in oauth2 and store it , so that when ETL jobs tries to run python scripts it do not tries to authenticate using any browser or user input .

Regards
Rahul
