PHP SoapClient的贝宝SetExpressCheckout验证失败

Question

这是当前的SOAP消息发送到SOAP贝宝API：

<?xml version="1.0" encoding="UTF-8"?> 

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:ns1="urn:ebay:apis:eBLBaseComponents" 
xmlns:ns2="ebl:SetExpressCheckoutRequestDetails" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:ns3="urn:ebay:api:PayPalAPI" 
xmlns:ns4="ebl:UserIdPasswordType"> 

<SOAP-ENV:Header> 
<ns3:RequesterCredentials xsi:type="ns4:UserIdPasswordType"> 
     <Username>xxxxx</Username> 
     <Password>xxxxx</Password> 
     <Signature>xxxxx</Signature> 
    </ns3:RequesterCredentials> 
</SOAP-ENV:Header> 

<SOAP-ENV:Body> 
<ns3:SetExpressCheckoutReq> 
    <ns3:SetExpressCheckoutRequest> 

     <ns1:Version>84.0</ns1:Version> 

       <ns1:SetExpressCheckoutRequestDetails 
       xsi:type="ns2:SetExpressCheckoutRequestDetailsType"> 

       <ReturnUrl>url_to_/success.paypal.php</ReturnUrl> 
       <CancelUrl>url_to_/cancel.paypal.php</CancelUrl> 
       <LocaleCode>US</LocaleCode> 

       </ns1:SetExpressCheckoutRequestDetails> 

    </ns3:SetExpressCheckoutRequest> 
    </ns3:SetExpressCheckoutReq> 
</SOAP-ENV:Body> 

</SOAP-ENV:Envelope> 

我实例化这个PHP5 SoapClient的：

//Endpoint 
$location = 'https://api-3t.sandbox.paypal.com/2.0/'; 
$uri = 'urn:ebay:api:PayPalAPI'; 

//SoapClient options 
$options = array('trace' => 1, 'exceptions' => 1, 'location'=>$location, 'uri'=>$uri); 

//My Soap Client 
$client =new SoapClient('https://www.sandbox.paypal.com/wsdl/PayPalSvc.wsdl',$options); 

但是，当我打电话SetExpressCheckout贝宝SOAP服务，我收到以下肥皂信息：

Ne尽管如此，我用我的企业帐户测试的API凭证... 我不明白为什么我的代码不起作用。

错误是：'您无权进行此API调用'，但它有可能如何？因为我使用正确的端点服务（沙箱）？

有人可以帮助我吗？

Answer 1

如果要连接到Sandbox API端点，则必须使用沙盒测试帐户的API凭据。
您可以通过https://developer.paypal.com/>测试帐户>预先配置来创建测试帐户。
