Question

我正在尝试使用PayPal的REST API创建发票，但我收到了身份验证错误。我知道这意味着我的凭据不正确，但事情是我的凭据是正确的，我100％肯定。我尝试创建新的沙盒帐户并输入新的详细信息，但我仍然收到相同的错误。我正在粘贴代码，请看一下并告诉我有什么问题。

Answer 1

导致该错误代码的事情非常少。传递明显，不正确或错误的凭据。不太明显，将实时站点凭据传递给测试端点，或将测试凭据传递给实时端点。

您说您使用的是Sandbox凭据，因此您需要确保传递给REST测试端点。（https://api.sandbox.paypal.com用于测试模式，或https://api.paypal.com用于直播）
