Create a card on file - an existing card that has been tokenized and stored in a digital wallet. The token is then used for payment transactions to avoid exposing sensitive data like the card's PAN and CVV.

Unless indicated otherwise (skip_validation = true), this endpoint generates a validation - a random transacation amount between 1.00 and 5.00 (later chargebacked) is created for the cardholder to approve, which requires them to log into an online banking account. The cardholder has up to 3 tries and 96 hours to input the correct amount. If the validation fails, the card is deleted from the wallet.

The card can be a Pismo-issued card or an external card. The card is added to the customer's digital wallet.

This endpoint generates a Card on file created event and, if skip_validation = false, a Card on file validation result received event.

Note: This is a PCI endpoint, use the https://gw-pci.pismolabs.io environment.
