Sample - Stripe API
POST/v1/customers/{customer}

Update a customer

Updates an existing customer using only the fields supplied in the request. Change contact, billing, payment source, invoice, balance, or metadata settings as needed, while omitted fields remain unchanged. Supplying a new source can retry eligible past-due subscription invoices, whereas changing default_source does not trigger that retry behavior.

  • RetriesRetries up to 2×, 500ms backoff, 30s timeout.
  • IdempotentThe SDK sends Idempotency-Key, so a retried request is only applied once.

addressobjectoptional
The customer's address.
balanceintegeroptional
The current balance, if any, that's stored on the customer in their default currency. If negative, the customer has credit to apply to their next invoice. If positive, the customer has an amount owed that's added to their next invoice. The balance only considers amounts that Stripe hasn't successfully applied to any invoice. It doesn't reflect unpaid invoices. This balance is only taken into account after invoices finalize. For multi-currency balances, see [invoice_credit_balance](https://docs.stripe.com/api/customers/object#customer_object-invoice_credit_balance).
business_namestringoptional
The customer's business name.
cash_balanceobjectoptional
The current funds being held by Stripe on behalf of the customer. You can apply these funds towards payment intents when the source is "cash_balance". The `settings[reconciliation_mode]` field describes if these funds apply to these payment intents manually or automatically.

currencystringoptional
Three-letter [ISO code for the currency](https://stripe.com/docs/currencies) the customer can be charged in for recurring billing purposes.
customer_accountstringoptional
The ID of an Account representing a customer. You can use this ID with any v1 API that accepts a customer_account parameter.
default_sourcestringoptional
ID of the default payment source for the customer. If you use payment methods created through the PaymentMethods API, see the [invoice_settings.default_payment_method](https://docs.stripe.com/api/customers/object#customer_object-invoice_settings-default_payment_method) field instead.
delinquentbooleanoptional
Tracks the most recent state change on any invoice belonging to the customer. Paying an invoice or marking it uncollectible via the API will set this field to false. An automatic payment failure or passing the `invoice.due_date` will set this field to `true`. If an invoice becomes uncollectible by [dunning](https://docs.stripe.com/billing/automatic-collection), `delinquent` doesn't reset to `false`. If you care whether the customer has paid their most recent subscription invoice, use `subscription.status` instead. Paying or marking uncollectible any customer invoice regardless of whether it is the latest invoice for a subscription will always set this field to `false`.

An arbitrary string attached to the object. Often useful for displaying to users.

If negative, the customer has an amount owed that's added to their next invoice denominated in that currency. These balances don't apply to unpaid invoices. They solely track amounts that Stripe hasn't successfully applied to any invoice. Stripe only applies a balance in a specific currency to an invoice after that invoice (which is in the same currency) finalizes.

The prefix for the customer used to generate unique invoice numbers.
