We are migrating to Clover payments from another payment processor. Our application allows users to save payment methods. Moving forward we'll use Clover's iframe and save the card token as a Clover customer so it can be charged in the future.
How can we migrate the existing card data we have stored into Clover? We're trying to use the https://docs.clover.com/reference/create-card-token endpoint, but we don't have the CVV to send. Is it possible to create a card without the CVV?
