The customer type.

• address The customer's address.
• balance Current balance, if any, being stored on the customer. If negative, the customer has credit to apply to their next invoice. If positive, the customer has an amount owed that will be added to their next invoice. The balance does not refer to any unpaid invoices; it solely takes into account amounts that have yet to be successfully applied to any invoice. This balance is only taken into account as invoices are finalized.
• cash_balance The current funds being held by Stripe on behalf of the customer. These funds can be applied towards payment intents with source "cash_balance".The settings[reconciliation_mode] field describes whether these funds are applied to such payment intents manually or automatically.
• created Time at which the object was created. Measured in seconds since the Unix epoch.
• currency Three-letter ISO code for the currency the customer can be charged in for recurring billing purposes.
• default_source ID of the default payment source for the customer.

If you are using payment methods created via the PaymentMethods API, see the invoice_settings.default_payment_method field instead.

• delinquent When the customer's latest invoice is billed by charging automatically, delinquent is true if the invoice's latest charge failed. When the customer's latest invoice is billed by sending an invoice, delinquent is true if the invoice isn't paid by its due date.

If an invoice is marked uncollectible by dunning, delinquent doesn't get reset to false.

• invoice_credit_balance The current multi-currency balances, if any, being stored on the customer.If positive in a currency, the customer has a credit to apply to their next invoice denominated in that currency.If negative, the customer has an amount owed that will be added to their next invoice denominated in that currency. These balances do not refer to any unpaid invoices.They solely track amounts that have yet to be successfully applied to any invoice. A balance in a particular currency is only applied to any invoice as an invoice in that currency is finalized.
