Hi Radu, The OAuth setup <https://developers.google.com/adwords/api/docs/guides/first-api-call#set_up_oauth2_authentication> is only required to be done once (provided the tokens are valid and credentials don't change). If your application is making calls against user's account, the user will need to authorize the application once which will generate the authorization code during the OAuth setup. You might have used this authorization code to further generate the access token and refresh token. Access tokens are short lived and refresh tokens are long lived (usually years). Your application could save this refresh token and make use of it to make any futhure API calls.
Once the above setup is done, if you make an API call to CustomerService.getCustomers() <https://developers.google.com/adwords/api/docs/reference/v201710/CustomerService#getcustomers> without specifying the client customerId in the header, the API will return all the customers directly accessible by the user authenticating the call. If you have any additional questions, could you please create a new thread?
