激活应用返回的费用ID 404 Shopify？

Question

我正在按照https://help.shopify.com/en/api/guides/charging-for-your-app/guides/implement-billing-model#implement-the-applicationcharge-resource

在我的应用中实施结算

有了这个，我已经能够生成费用ID，但是在激活费用ID的过程中，我找不到了404。

充电端点类似https://store.myshopify.com/admin/api/2019-04/application_charges/9878536240/activate.json

身体如下

{
  "application_charge": {
    "id": 9878536240,
    "name": "iPod Cleaning",
    "api_client_id": 755357713,
    "price": "5.00",
    "status": "accepted",
    "return_url": "http:\/\/google.com",
    "created_at": "2017-07-19T12:24:00-04:00",
    "updated_at": "2017-07-19T12:24:00-04:00",
    "test": null,
    "charge_type": null,
    "decorated_return_url": "http:\/\/google.com?charge_id=675931192"
  }
}

每次我都找不到404错误。我想念什么或做错什么了？
