但是我得到如下错误

<Source>clsEVS:GetAPIRegistrationInfo</Source>
<Description>MasterMID not found in database.  </Description>

我还需要通过什么或我在这方面遗漏了什么？我从路径 https://www.usps.com/business/web-tools-apis/evs-label-api.htm#_Toc487532684 获取了引用。

Answer 1

您似乎使用了提供的示例 MID 示例，而不是提供您的实际 MID。当您 1. 完全删除 MID，或 2. 提供您的实际 MID 时，请求是否成功？
