A card "verification-only" will perform a real-time authorization on the credit card for the amount of $0.00. The card-network will verify if the card exists, but cannot guarantee that there is an available balance on the card. Verified cards will be tokenized and saved in the vault.
Full Card Numbers Are Restricted
Please note that this request requires you to send full card number, which is restricted to most merchants without requesting an exception. Instead, we recommend using Helcim.js to verify and tokenize full card numbers.
