Appcharge

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).

Appcharge publishes 17 APIs on the APIs.io network, including Assets API, Authentication API, Badges API, and 14 more. Tagged areas include Company, Payments, Monetization, Merchant of Record, and Mobile Games.

The Appcharge catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Appcharge’s developer surface includes documentation, API reference, support, engineering blog, signup flow, authentication, changelog, and 32 more developer resources.
