调用Walmart Shipment API遇Internal Server Error问题求助

我在对接Walmart Shipment API时碰到了系统内部错误。已经确认所有请求头配置无误——生成的token在getOrders API中能正常使用，但调用shipment API时却失效了。

请求详情 #

API URL #

https://sandbox.walmartapis.com/v3/orders/{PurchaseOrderId}/ship

请求头 #

• Authorization: Basic Base64编码(clientId:clientSecret)
• WM_SEC.ACCESS_TOKEN: <walmart_access_token>
• WM_QOS.CORRELATION_ID: 唯一标识ID
• WM_SVC.NAME: Walmart Marketplace
• WM_MARKET: mx
• WM_CONSUMER.CHANNEL.TYPE: Walmart
• grant_type: test

请求体 #

{
  "shipments": [
    {
      "shipmentLines": [
        {
          "primeLineNo": "2",
          "shipmentLineNo": "2",
          "quantity": {
            "unitOfMeasurement": "EACH",
            "amount": "2"
          }
        }
      ],
      "trackingNumber": "1234556",
      "trackingURL": "http://www.otherCarrier.com",
      "carrier": "Other"
    }
  ]
}
