Getting Started
What is the Gamma API?
Gamma's Generate API allows users to create presentations programmatically without using the Gamma app directly. This is perfect for users who want to:
Automate their workflows using tools like Zapier, Make, or Workato
Integrate beautiful presentation generation into their own applications
Create presentations at scale through backend code integration
Is the API ready?
💎 Important: Our Generate API is currently in beta. Anyone with a Pro account can access the API with usage limits today.
How do I get access?
To access the Gamma API:
You must have a Gamma Pro account. If you're not currently a Pro user, upgrade to Pro to access the API.
Generate an API key:
Go to "Settings and Members" in your Pro account
Navigate to the "API key" tab
Click "Create API key" to generate your key
Copy and securely store your API key
Start using the API with your favorite automation tools or integrate directly into your backend code.

FAQs & Common Issues
Can I share my API keys with others?
API keys should be kept secure and not shared. Generate separate keys for different use cases if needed.
Why can't I copy my API key again?
For security reasons, API keys are only shown once when generated. If you lose your key, you'll need to generate a new one.
Can I generate multiple API keys?
Yes, you can create multiple API keys for different projects or use cases through your account settings.
Will I have higher rate limits once the API is GA?
Yes, when the API exits beta, we'll offer options for higher usage limits with usage-based pricing.
