# Gamma Core Workflow B: Templates & Export ## Overview Use Gamma's template-based generation (`POST /v1.0/generations/from-template`) and export retrieval (`GET /v1.0/generations/{id}/files`) endpoints. Template generation lets you replicate a single-page gamma template across multiple variations. Export retrieval gives you downloadable PDF, PPTX, and PNG files. ## Prerequisites - Completed `gamma-core-workflow-a` - A template gamma with exactly one page (created in the Gamma app) - Understanding of the generate-poll-retrieve pattern ## Key Concepts - **Template gamma**: A regular gamma with exactly one page, used as a repeatable template - **gammaId**: Found in the gamma URL or copied from the app - **Export URLs**: Temporary download links returned after generation — download promptly as they expire ## Instructions ### Step 1: Create from Template ```typescript import { createGammaClient, pollUntilDone } from "./lib/gamma"; const gamma = createGammaClient({ apiKey: process.env.GAMMA_API_KEY! }); // POST /v1.0/generations/from-template // The template gamma MUST have exactly one page async function generateFromTemplate( templateGammaId: string, prompt: string, options: { themeId?: string; exportAs?: "pdf" | "pptx" | "png"; imageStyle?: string; } = {} ) { const { generationId } = await gamma.generateFromTemplate({ gammaId: templateGammaId, prompt, themeId: options.themeId, exportAs: options.exportAs, imageOptions: options....
