// End PayPal account credentials

// User info

$pp->request['email'] = 'The users email address';

$pp->request['creditcardtype'] = 'Visa'; // Visa, Mastercard, Discover, Amex
$pp->request['acct'] = ''; // Credit card number
$pp->request['expdate'] = str_pad('8',2,'0', STR_PAD_LEFT)  .'2020'; // Expiration month and full year. Pad the month with 0. Month should be 1-12. This example is 8/2020.
// End user info

// Product info
$pp->request['countrycode'] = 'US';
$pp->request['billingperiod'] = 'Month'; // Bill per month
$pp->request['billingfrequency'] = 1; // How many times to bill per billing period.. This example is once per month
$pp->request['currencycode'] = 'USD';
$pp->request['amt'] = 9.95; // Amount to bill every month
$pp->request['initamt'] = 0.00; // Setup fee.. One time on account creation
$pp->request['taxamt'] = $pp->request['amt'] * .07; // Replace .07 with your tax percentage. 0 for no tax.
$pp->request['desc'] = 'Super Deluxe Package'; // The description of your product for reporting in your account
$pp->request['profilestartdate'] = gmdate('Y-m-d\TH:i:s\Z');
$pp->request['totalbillingcycles'] = '3'; // How many billing cycles. 0 for no expiration. This example is for 3 total months of billing.
$pp->request['payerstatus'] = 'verified';
// End product info

Answer 1

这是因为以下代码中的API凭据不正确。

$pp->request['user'] = 'xxx';
$pp->request['pwd'] = 'xxx';
$pp->request['signature'] = 'xxx';

您可以按照以下步骤查找您的API凭据：

对于沙盒帐户：

访问https://developer.paypal.com/并登录，然后访问以下网址：

https://developer.paypal.com/developer/accounts

点击用于测试的商家帐户，然后点击＆＃34;个人资料＆＃34;帐户下的链接。然后单击＆＃34; API凭据＆＃34;选项卡，您将找到API凭据。

对于真实账户：

登录www.paypal.com，转到个人资料 - >销售工具 - ＆gt; API访问，点击＆＃34;请求API凭据＆＃34;链接，然后选择＆＃34;请求API签名＆＃34;然后单击＆＃34;同意并提交＆＃34;。然后，您可以在最后一页找到您的API用户名，API密码和API签名。
