Hi,
Thank you for posting your concern.
The
USER_PERMISSION_DENIED error occurs when authenticating as a user with access to a manager account but not specifying
login-customer-id in the request. With this, you need to specify the
login-customer-id as the manager account ID without hyphens (-). Client libraries have built in support for this, or see our
guide.
Let me know if you have further questions.
Regards,
