Hello André, If you are using OAuth credentials from a manager account and are accessing a related customer account the login-customer-id header to the customer ID of the manager account. If you are using OAuth credentials from a manager account, then you should be able to find this by logging into your Google Ads manager account on the top right corner. To pull the specific ad group details in a client account, you will need to use the client customer Id here and then pull the specific ad groups from the account.
Let me know if you have any concerns.
