Using paypal pro for repeat nonrecurring charges

Is there anyway开发者_开发技巧 to use paypal pro to allow a customer to make repeat purchases without setting up a recurring payment. The use case is a customer who does not have a paypal account enters payment info once for a purchase. When they return to the website, it would be nice if they didn't have to enter payment details again. This is possible for recurring payments but I see no way of doing this for repeat one-time transactions.

I was looking for similar functionality and found DoReferenceTransaction API operation. It allows to use details from another transaction which is specified by ReferenceId parameter. For instance one can use TransactionId returned by DoDirectPayment as ReferenceId for DoReferenceTransaction
