Wordpress 如何使用RESTAPI向客户添加元数据？

我需要使用woocommerce rest api向客户概要文件添加元数据（CNPJ）； 我正在从ionic应用程序发送此数据：

  {
  "customer": {
    "billing_address": {
      "company": "Company Name ABC",
      "address_1": "St. ABC ",
      "address_2": "121",
      "state": "NY",
      "city": "New York",
      "postcode": "99000-000",
      "phone": "345456456",
      "country": "US",
      "email": "email@gmail.com",
      "first_name": "Bob",
      "last_name": "Doe"
    },
    "shipping_address": {
      "first_name": "Bob",
      "last_name": "Doe"
      "company": "Company Name ABC",
      "address_1": "St. ABC ",
      "address_2": "121",
      "state": "NY",
      "city": "New York",
      "postcode": "99000-000",
      "country": "US"
    },
    "meta_data": [
      {
        "key": "cnpj",
        "value": "123123123123123"
      }
    ],
    "first_name": "Bob",
      "last_name": "Doe"
    "email": "email@gmail.com",
    "password": "123456",
    "username": "bobdoe"
  }
}

客户已成功注册，但元数据未成功注册。 ionic应用程序正在使用/wc api/v3/customers端点

怎么了？是否可以使用woocommerce REST API将元数据保存到客户配置文件中？

我也遇到了同样的问题，我可以使用以下说明解决此问题：

注意：我在wordpress中使用这个插件为额外字段创建巴西额外的签出字段
