  title: Appcharge Assets Localization API
  version: 1.0.0
  description: Appcharge is a monetization platform for mobile games, providing a direct-to-consumer (D2C) web store, mobile Checkout SDK, and Payment Links so publishers can sell in-game offers outside the app stores. This API covers checkout sessions, refunds, coupons and promo codes, price localization, financial and analytics reporting, web store offers (bundles, daily bonuses, rolling/special offers, progress bars, reward calendars, triggered popups), offer components (products, badges, offer designs), game-portal content, media assets, translations, and player personalization/authentication callbacks. Authentication uses the x-publisher-token header; webhooks are signed with an HMAC-SHA256 signature.
