Google Express – Заказ счетов-фактур: createchargeinvoice

Я интегрирую Google Express с Magento, но API создания счетов-фактур не работает. Я попытался создать счет из опции «Попробовать этот API» продавца Google, но он выдает следующую ошибку:

{
 "error": {
  "errors": [
   {
    "domain": "content.ContentErrorDomain",
    "reason": "invalid_transition",
    "message": "The requested order is not supported by orderinvoices service"
   }
  ],
  "code": 400,
  "message": "The requested order is not supported by orderinvoices service"
 }
}

Документ API createchargeinvoice: https://developers.google.com/shopping-content/v2/reference/v2/orderinvoices/createchargeinvoice
