Appcharge is a monetization and payments platform (merchant of record) for mobile game publishers. It lets studios sell in-game offers direct-to-consumer outside the app stores through a hosted web store, a mobile Checkout SDK, and Payment Links — covering checkout sessions, price localization, coupons and promo codes, refunds, web-store offers (bundles, daily bonuses, rolling/special offers, progress bars, reward calendars, triggered popups), offer components, game-portal content, media assets, translations, financial and analytics reporting, and player personalization/authentication callbacks. The REST API authenticates with an x-publisher-token API-key header; webhooks and Appcharge-to-publisher callbacks are HMAC-SHA256 signed with a replay window; and a hosted MCP server exposes agent access over OAuth 2.0 (authorization_code + PKCE).
