# Gamma Install & Auth ## Overview Configure authentication for the Gamma Generate API v1.0 (GA since Nov 2025). Gamma uses a REST API at `https://public-api.gamma.app/v1.0/` — there is no official SDK package. All requests authenticate via the `X-API-KEY` header. ## Prerequisites - Gamma Pro account or higher (API access requires Pro+) - Node.js 18+ or Python 3.10+ for wrapper code - `curl` or HTTP client library ## Instructions ### Step 1: Generate API Key 1. Log in at [gamma.app](https://gamma.app) 2. Navigate to **Settings and Members** (dropdown, upper-left) 3. Select the **API key** tab 4. Click **Create API key** 5. Copy and securely store the key — it will not be shown again ### Step 2: Configure Environment ```bash # Set environment variable (add to .env or shell profile) export GAMMA_API_KEY="gma_your_api_key_here" # .env file approach echo 'GAMMA_API_KEY=gma_your_api_key_here' >> .env ``` ### Step 3: Verify Connection ```bash # Quick verification with curl curl -s -o /dev/null -w "%{http_code}" \ -H "X-API-KEY: ${GAMMA_API_KEY}" \ https://public-api.gamma.app/v1.0/themes # 200 = authenticated, 401 = invalid key ``` ### Step 4: First API Call (Node.js) ```typescript // gamma-client.ts — thin wrapper around the REST API const GAMMA_BASE = "https://public-api.gamma.app/v1.0"; interface GammaConfig { apiKey: string; baseUrl?: string; } export function createGammaClient(config: GammaConfig) { const headers = { "X-API-KEY": config.apiKey, ...
