Sale Method
This method sends a Sale transaction to PayPal.
Object Oriented Interface
public function doSale();
Procedural Interface
inpaypal_directpayment_do_sale($res);
Remarks
There are two types of transactions, Sales and Authorizations. In a Sale, the transaction is automatically captured, and funds are automatically deposited into your PayPal account. However, in the case of an authorization (using the Authorize method), funds are not automatically captured. You must manually capture the funds using the ReAuthCapture class.
