我正在尝试实施PayPal Adaptive Payments API.进入标题我应该包括这些信息:
headers.put("X-PAYPAL-SECURITY-USERID", "tok261_biz_api.abc.com");
headers.put("X-PAYPAL-SECURITY-PASSWORD","1244612379");
headers.put("X-PAYPAL-SECURITY-SIGNATURE","lkfg9groingghb4uw5"
headers.put("X-PAYPAL-DEVICE-IPADDRESS", "168.212.226.204");
headers.put("X-PAYPAL-REQUEST-DATA-FORMAT", "NV");
headers.put("X-PAYPAL-RESPONSE-DATA-FORMAT", "NV");
headers.put("X-PAYPAL-APPLICATION-ID", "APP-80W284485P519543T");
我为买家和卖家创建了测试帐户.但我真的不知道前三项是什么.我找不到那些信息.有多个网站developer.paypal.com,x.com所以令人困惑.我不知道应该使用哪个USERID和SIGNATURE.
