Hi Angel, Could you confirm if you are generating OAuth2 credentials for an AdWords account? If yes, you can follow the steps mentioned in this guide <https://developers.google.com/adwords/api/docs/guides/authentication#webapp> for the Web App flow. Once you have set up your credentials, your application should then be able to access the APIs you wish to use without having to manually specify them in each request.
I hope this helps and feel free to write back if you require further information.
