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)

Instructions

Minimal curl Example

# Step 1: Create generation
GENERATION=$(curl -s -X POST \
  "https://public-api.gamma.app/v1.0/generations" \
  -H "X-API-KEY: ${GAMMA_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Create a 5-card presentation about the benefits of AI in business",
    "outputFormat": "presentation"
  }')

GEN_ID=$(echo "$GENERATION" | jq -r '.generationId')
echo "Generation started: $GEN_ID"

# Step 2: Poll until complete (every 5 seconds)
while true; do
  STATUS=$(curl -s \
    "https://public-api.gamma.app/v1.0/generations/${GEN_ID}" \
    -H "X-API-KEY: ${GAMMA_API_KEY}")
  STATE=$(echo "$STATUS" | jq -r '.status')
