# Account Verifications

Verify your customer's account to maximize your authentication rates.

With our Verifications API you are able to perform an [intelligent verification](/products/card-verifications/v5/verifications#intelligent-verification), a [dynamic verification](/products/card-verifications/v5/verifications#dynamic-verification) and query [previous verifications](/products/card-verifications/v5/verifications#query-verification).

When you want to verify your customer's account before taking a payment, you must submit a verifications request to our Verifications API. For more information, see [verifying an account](/products/card-verifications/v5/verifications#verifying-an-account).

If we need to charge your customer, our API applies a nominal authorization (intelligent verification/dynamic verification). The authorization is then cancelled before your customer is charged.
