You can get more information about a payment method nonce by passing the nonce string as an argument to the find method.

Unlike other calls, a find call does not consume the payment method nonce – instead, it returns the nonce string back to your server along with 3D Secure information such as liabilityShifted and liabilityShiftPossible. This can be used for server-side risk checking before creating transactions.

$paymentMethodNonce = $gateway->paymentMethodNonce()->find('nonce_string');
$info = $paymentMethodNonce->threeDSecureInfo;
if (empty($info)) {
  // This means that the nonce was not 3D Secured

If the payment method nonce can't be found, you'll receive a Braintree\Exception\NotFound exception.
