Hi, Thank you for raising your concern.
To summarize the authentication on Google Ads API, if the OAuth2 credentials you are using were created by a user which is a user of your MCC/manager account, then you would need to include the MCC's customer ID as the login-customer-id in your properties file. Please refer to this document to read more information about login-customer-id. Also, the process that you've mentioned in your latest reply appears to be the proper way of authenticating in Google Ads API.
