Fetch Card Authentication

GET 
/card_auths/:id

Retrieve a card authentication and its result once the cardholder has finished.

The result object is returned only with secret key authentication. A publishable key may fetch the authentication for 15 minutes after creation — for example to check the status after the cardholder is redirected back — but result is always null on those responses.
