//! Use the Cards API to save a credit or debit card on file.
//!
//! You can use the CreateCard endpoint to save a credit or debit card to a Square account.
//! Developers can integrate the Cards API in their application to let Square sellers:
//!
//! * Save a card that can be charged by any Square seller who uses your application. Your
//! application specifies the organization access token in the `CreateCard` request.
//! * Save a card that can be charged by a single Square seller. Your application specifies the
//! access token of the specific seller account in the `CreateCard` request.
//!
//! The Cards API also supports other endpoints to manage the cards.
