已执行的排查步骤 #

• 确认x-amz-access-token正确且未过期
• 验证x-amzn-shipping-business-id准确无误
• 反复核对Endpoint URL及请求头信息

排查建议 #

1. 区域与业务ID匹配检查：当前调用的是欧盟区域沙箱Endpoint，但x-amzn-shipping-business-id为印度区域的AmazonShipping_IN，二者不匹配。欧盟区域对应的业务ID应为AmazonShipping_EU；若测试印度业务，需切换至印度区域沙箱Endpoint：https://sandbox.sellingpartnerapi-fe.amazon.com/shipping/v2/shipments/rates。
2. 权限范围验证：确认生成x-amz-access-token时申请的权限scope包含sellingpartnerapi::shipping，沙箱环境需单独配置对应权限。
3. 签名流程检查：Postman中需完整配置AWS Signature Version 4签名，沙箱接口同样要求签名验证，检查是否遗漏Authorization、x-amz-date等签名相关请求头。
4. 卖家账户权限确认：确保生成Token的沙箱卖家账户已开通对应区域的亚马逊物流服务，且账户状态正常。
5. 测试数据合规性：检查请求体中的地址、业务参数是否符合对应区域沙箱的测试规范，比如印度地址需对应印度区域接口。
