Paypal Express 结帐 - 未获取结算协议(protocol) ID

Question

我正在尝试使用 Paypal Expresscheckout 计费协议(protocol) ID 测试引用交易。但我根本没有得到 BAID。以下是我正在调用的电话:

第 1 步:setExpresschecout 调用:

---

Request 
    Endpoint URL: https://api-3t.sandbox.paypal.com/nvp
    HTTP method: POST
------------------------------------------------------------
POST data:
USER=insert_merchant_user_name_here
&PWD=insert_merchant_password_here
&SIGNATURE=insert_merchant_signature_value_here
&METHOD=SetExpressCheckout
&VERSION=93
&PAYMENTACTION=SALE     # type of payment
&AMT=19.95              # amount of transaction
&CURRENCYCODE=USD       # currency of transaction
&RETURNURL=<return_url>  # URL of your payment confirmation page
&CANCELURL= <cancel_url>  # URL redirect if customer cancels payment
&L_BILLINGTYPE0=MerchantInitiatedBilling

-------------------
Response
----------------------
token=EC-7NH28597U8423791A 
-----------------------

它将我重定向到 Paypal 进行登录，并在单击“同意并付款”按钮后，将我重定向回带有 token 和 payerID 的站点。因为我不需要存储客户详细信息，所以我跳过 GetExpresschecout 调用并直接使用 token 和 PayedID 调用 doExpressCheckoutPayment。

STEP2 : 做Expresscheckoutpayment

USER=insert_merchant_user_name_here
&PWD=insert_merchant_password_here
&SIGNATURE=insert_merchant_signature_value_here
&METHOD=DoExpressCheckoutPayment
&VERSION=93
&PAYMENTACTION=SALE     # type of payment
&AMT=19.95              # amount of transaction
&CURRENCYCODE=USD       # currency of transaction
&TOKEN=token_value
&PAYERID=payer_id_received

这是回应。但它没有 BILLING 协议(protocol) ID。

仅供引用..paymentaction 设置为 SALE，因为我需要获取付款。

有什么错误的建议吗？

谢谢，普尼亚

Answer 1

您需要运行 CreateBillingAgreement 获取 BAID 的 API。这应该在您从 SetExpressCheckout API 获得 EC token 后完成。

P.S 引用交易应该在您的帐户上启用。
