Выдает авторизацию Paypal: не удается получить доступ к этому ресурсу

Я работаю на Paypal Marketplace. Я хочу создать продавца (учетную запись продавца) для своей учетной записи (партнерской учетной записи). Но когда я звоню POST https://api.sandbox.paypal.com/v1/customer/partner-referrals API, чем он выдает AUTHORIZATION_ERROR: Вам не разрешен доступ к этому ресурсу. Я передал токен в заголовке, генерируя его https://api.sandbox.paypal.com/v1/oauth2/token

Ниже данные, которые я передал, используя Почтальон:
