未提供公司信息时运单标签重复打印寄件人姓名问题咨询

问题背景 #

使用EasyPost API的one-call buy接口创建运单时，from_address仅传入name字段（未提供company），生成的运单标签会重复打印寄件人姓名。尝试显式传入"company": ""或"company": null后，重复问题仍未解决。

是否为预期行为？ #

这并非EasyPost API的默认行为，而是所使用承运商的标签模板规则导致的：当地址对象中无有效company值时，部分承运商的模板会自动将name字段内容填充到company的显示位置，最终造成姓名重复。

无需添加真实公司名的解决方法 #

• 拆分姓名字段：将from_address中的name拆分为first_name和last_name字段传入，承运商模板通常会正确解析这两个字段，避免重复填充。示例修改后的from_address：

  "from_address": {
    "city": "New York",
    "country": "US",
    "email": "sender@example.com",
    "first_name": "John",
    "last_name": "Doe",
    "phone": "1234567890",
    "state": "NY",
    "street1": "123 Main St",
    "street2": "",
    "zip": "10001"
  }
  

• 使用空白占位符：尝试传入"company": " "（单个空格）代替空字符串或null，部分承运商会忽略空白的company值，不再重复显示姓名。
• 联系EasyPost支持：确认当前使用的承运商标签模板是否支持自定义地址显示逻辑，通过EasyPost团队调整模板配置。
