问题描述
我使用Paypal搜索发票API成功发出了请求，该API会按预期返回发票详细信息。
我还想访问该发票上的明细（项目）。我相信这样做的方法是在请求的fields参数中指定“ items”，这将返回一个我可以访问以使用此数据的csv。
但是，尽管请求成功，但是给发票的URL（我想是csv所在的URL）具有以下错误：
{"name":"AUTHENTICATION_FAILURE","message":"Authentication Failed due to invalid authentication credentials or a missing Authorization header.","links":[{"href":"https://developer.paypal.com/docs/apI/Overview/#error","rel":"information_link"}]}
这是为什么？这是我的请求的详细输出：
