Paypal REST API - 信用卡验证，无需收费

Question

I am using the Paypal Rest API in my C# .Net Framework 4.5.1 to verify credit-card payments.

I want to be able to verify the credit card of a customer while registering them to my website. What I am currently doing is, I charge the customer $0.01 and refund it back right away in order to verify the credit-card.

I don`t think this is practically the right way to verfiy the credit card. So, is it possible to verify credit-cards directly (without charging anything) using the Paypal Rest API ?

Paypal has a sandbox mode where you can create fake users and do fake transactions
