Gamma Hello World

Overview

Generate your first presentation using Gamma's async Generate API. The workflow is: POST to create a generation, poll for status, then retrieve results (gammaUrl + exportUrl).

Prerequisites

• Completed gamma-install-auth setup
• Valid GAMMA_API_KEY environment variable
• Pro account with available credits

The Generate-Poll-Retrieve Pattern

All Gamma generations are asynchronous:

1. POST /v1.0/generations — submit content, receive generationId
2. GET /v1.0/generations/{generationId} — poll every 5s until completed or failed
3. Result — gammaUrl (view in app) + exportUrl (download PDF/PPTX/PNG)
