我使用Paypal Express Checkout API处理Paypal和VISA付款 我的代码将用户重定向到paypal页面，并在出现身份验证的表单之后。然后我继续进行身份验证，然后单击“立即付款”按钮 我被重定向到返回URL。显然一切似乎都没问题，但我从未收到商家账户上的钱，而且钱从未从买家账户中扣除。
以下是我请求令牌的代码：
private function _proceed_to_paypal($total_amount = false, $id_order = false, $description = false) {
if ($total_amount === false || $id_order === false) {
return false;
}
$this->load->library('paypal_functions');
$this->paypal_functions->init();
