integration - 如何在 Coupa 中发布带有附件的 cXML 发票？

Question

Coupa 引入了这种在 cXML 发票中包含附件的新功能。唯一的文档（我知道）说在 CXML 发票文件中包含代码（如下所述）。

Coupa 文档：

Coupa 文档的屏幕截图

谁能帮助我了解如何使用此文档发送 cXML 发票？在 cXML 发票（用于 Coupa）上包含附件的任何其他帮助将不胜感激。

提前致谢

Answer 1

正确，R18 允许您在发布 InvoiceDetailRequest cxml 时附加文件。在 R18 之前，您将通过 Coupa API 密钥通过 2 部分帖子附加。从 R18 开始，没有 API 密钥，您使用 header 。下面是你如何做到的。如果您有进一步的澄清问题，我将监控此页面。

1--您必须在 Content-ID 标头中指明 MIME 多部分媒体类型。这将触发我们的解析器来检索附件。

示例：内容类型：多部分/相关

2--必须在元素中传递属性。附件数据可以是服务器上文件的 url 或内容 id (cid)。如果执行 cid，该文件必须与 InvoiceDetailRequest 文档位于服务器上相同的文件夹结构中。在下面的示例中，我们附加了 2 个文件，一个文件和一个 url。

例子：

<Comments>
<Attachment><URL>cid:test.pdf</URL></Attachment>
<Attachment><URL>url</URL></Attachment>
</Comments>
</InvoiceDetailRequestHeader>

有关更多详细信息，请参阅 cxml.org 上的第 51 和 69 页。
