訂單生命週期 (購買後)

結帳完成並下單後，你必須使用 Webhook 將狀態更新推送至 Google。API 金鑰必須在查詢參數或標頭中傳送。

1. 訂單建立事件

• 觸發條件：訂單確認後 (status: processing) 立即傳送。
• 端點： POST /webhooks/partners/{partner_id}/events/order

酬載：你必須傳送完整的訂單實體。

{
  "ucp": { "version": "2026-01-01", "capabilities": [...] },
  "id": "order_789",
  "checkout_id": "checkout_xyz789",
  "line_items": [
    {
      "id": "line_1",
      "item":
        {
          "id": "product_12345",
          "title": "Running Shoes",
          "price": 10000
        },
      "quantity": { "total": 1, "fulfilled": 0 },
      "totals": [
        {"type": "subtotal", "amount": 10000},
        {"type": "total", "amount": 10000}
      ],
      "status": "processing"
    }
  ],
  "fulfillment": {
    "expectations": [
      {
        "id": "exp_1",
        "line_items": [{ "id": "line_1", "quantity": 1 }],
        "method_type": "shipping",
        "destination": {
          "street_address": "123 Main St",
          "address_locality": "Austin",
          "address_region": "TX",
          "address_country": "US",
          "postal_code": "78701"
        },
        "description": "Arrives in 2-3 business days",
        "fulfillable_on": "now"
      }
    ]
  },
  "permalink_url": "https://merchant.example.com/orders/789"
}

2. 訂單動態 (運送/取消)

• 觸發條件：訂單狀態更新時 (例如商品出貨或取消)。
• 規定：你必須再次傳送完整訂單實體，而不只是部分更新。

示例 (已出貨)：
