  title: Runa Payouts Balance API
  description: The Runa Payouts API provides a single integration point for digital reward and gift card distribution across 190+ countries with access to over 5,000 gift cards and payout options. The API supports creating orders in both synchronous (instant) and asynchronous (polling) modes, balance management, product catalog browsing by category and country, order estimation, and event webhooks for order completion and product updates. Authentication uses the X-Api-Key header. Use X-Idempotency-Key on order creation to prevent duplicate orders.
