如何在Coupa中过帐带有附件的cXML发票？

Question

Coupa引入了在cXML发票中包含附件的新功能。唯一的文档(据我所知)说，包括代码(下面提到)在CXML发票文件。

Coupa文档：

谁能帮助我理解如何在发送cXML发票时使用本文档？任何其他帮助包括在cXML发票上的附件(为Coupa)将不胜感激。

提前感谢

Answer 1

正确，R18允许您在发布InvoiceDetailRequest cxml时附加文件。在使用R18之前，您可以通过Coupa API密钥通过两部分post进行连接。从R18开始，没有API key，而是使用头部。下面是你如何做到这一点。我将监控此页面，以防您有进一步的澄清问题。

1--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: Content-type: multipart/related

2--必须在元素中传递属性。附件数据可以是您服务器上的文件的url或内容id (cid)。如果执行cid，文件必须与InvoiceDetailRequest文档驻留在服务器上相同的文件夹结构中。在下面的例子中，我们附加了两个文件，一个文件和一个url。

示例：

<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页和第69页。
