/**
 * A customer is a buyer of your products, and the other party to the billing relationship.
 *
 * In Orb, customers are assigned system generated identifiers automatically, but it's often desirable to have these
 * match existing identifiers in your system. To avoid having to denormalize Orb ID information, you can pass in an
 * `external_customer_id` with your own identifier. See
 * [Customer ID Aliases](/events-and-metrics/customer-aliases) for further information about how these
 * aliases work in Orb.
 *
 * In addition to having an identifier in your system, a customer may exist in a payment provider solution like
 * Stripe. Use the `payment_provider_id` and the `payment_provider` enum field to express this mapping.
 *
 * A customer also has a timezone (from the standard [IANA timezone database](https://www.iana.org/time-zones)), which
 * defaults to your account's timezone. See [Timezone localization](/essentials/timezones) for
 * information on what this timezone parameter influences within Orb.

  /**
   * ## The customer balance
   *
   * The customer balance is an amount in the customer's currency, which Orb
   * automatically applies to subsequent invoices. This balance can be adjusted
   * manually via Orb's webapp on the customer details page. You can use this balance
   * to provide a fixed mid-period credit to the customer. Commonly, this is done due
   * to system downtime/SLA violation, or an adhoc adjustment discussed with the
   * customer.
   *
   * If the balance is a positive value at the time of invoicing, it represents that
   * the customer has credit that should be used to offset the amount due on the next
   * issued invoice. In this case, Orb will automatically reduce the next invoice by
   * the balance amount, and roll over any remaining balance if the invoice is fully
   * discounted.
   *
   * If the balance is a negative value at the time of invoicing, Orb will increase
   * the invoice's amount due with a positive adjustment, and reset the balance to 0.
   *
   * This endpoint retrieves all customer balance transactions in reverse
   * chronological order for a single customer, providing a complete audit trail of
   * all adjustments and invoice applications.
