# Gamma API Patterns ## Overview Gamma has no published SDK — all interaction is via REST at `https://public-api.gamma.app/v1.0/`. This skill provides production-grade patterns for typed clients, generation helpers, polling, template workflows, and error handling. ## Prerequisites - Completed `gamma-install-auth` setup - TypeScript project with `fetch` (Node.js 18+) - Understanding of the generate-poll-retrieve workflow ## Instructions ### Step 1: Typed Client Singleton ```typescript // lib/gamma.ts const GAMMA_BASE = "https://public-api.gamma.app/v1.0"; interface GammaConfig { apiKey: string; baseUrl?: string; timeoutMs?: number; } // Types based on actual API responses interface GenerateRequest { content: string; outputFormat?: "presentation" | "document" | "webpage" | "social_post"; themeId?: string; exportAs?: "pdf" | "pptx" | "png"; textMode?: "generate" | "condense" | "preserve"; textAmount?: "brief" | "medium" | "detailed" | "extensive"; imageOptions?: { style?: string }; sharingOptions?: { workspaceAccess?: "noAccess" | "view" | "comment" | "edit" | "fullAccess"; externalAccess?: "noAccess" | "view" | "comment" | "edit" | "fullAccess"; }; folderIds?: string[]; } interface GenerateResult { generationId: string; status: "in_progress" | "completed" | "failed"; gammaUrl?: string; exportUrl?: string; creditsUsed?: number; } let instance: ReturnType<typeof createGammaClient> | null = null; export function getGamma() { ...
