Square API

You are viewing an old version of the API
Cards

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.
