Turn your Patreon into your storefront. Patreon Access lets players log in with their own Patreon account straight from your game — one browser click, no server, no client secret, no website to maintain. Read their entitled tier in Blueprint or C++ and gate characters, chapters, or cosmetics behind any pledge threshold. Price-based checks survive tier renames, a 40-day offline cache keeps paying patrons unlocked on the go, and the RFC-8252 loopback OAuth flow with CSRF protection keeps it secure. Register a free OAuth client, paste your Client ID, ship it.

Features:

• In-game Patreon login via OAuth 2.0 authorization-code flow with loopback redirect (RFC 8252 native-app pattern) — no embedded browser, no backend

• Fully asynchronous, delegate-driven API — no game-thread blocking

• CSRF-safeguarded callback: each login carries a single-use random state nonce; forged or spurious localhost requests can neither complete nor cancel a pending login

• No client secret shipped; public-client token exchange (client id only)

• Membership and entitled tiers (id, title, pledge amount in cents) exposed to Blueprint and C++

• Recommended cents-threshold gating that survives tier renames on your Patreon page

• Offline grace via local cache in a plugin-owned save slot (configurable lifetime, default 40 days)

• Silent refresh-token renewal and optional auto-refresh at boot

• OnMembershipUpdated / OnMembershipFailed Blueprint-assignable delegates

• Endpoint overrides in Project Settings — route the token exchange through your own proxy later with zero code changes

• Dev console commands (Patreon.Login, Patreon.Refresh, Patreon.Status, Patreon.Logout), compiled out of Shipping builds
