Hi Ľubo, Thank you for reaching out. This error indicating that you don’t have permission to access the customer most probably comes from the fact that you were not using the email of account 438-671-3590 to generate the OAuth2 credentials, however, you were trying to access this manager account. Please use the email of 438-671-3590 to generate the OAuth2 credentials and try it again. Also keep in mind that you are supposed to add campaigns to a client customer account rather than a manager account.
