API keys authenticate your application with GT services. You'll find the API Keys page in the project sidebar.

Production keys

Production API keys are 72-character strings starting with gtx-api-. Use these in your deployed application.

Creating a production key

1. Click Create API Key
2. Enter a name for the key (e.g., "Production", "Web App")
3. Copy the full key immediately—you won't be able to see it again
4. Store it securely (environment variables, secrets manager, etc.)

Managing keys

• Preview: Shows a truncated version of the key for identification
• Created At: When the key was generated
• Last Used: When the key was last used (helps identify stale keys)
• Delete: Revoke a key you no longer need

Development keys

Development keys are for local development and preview environments. They start with gtx-dev- and should never be used in production.

Development keys let you test translations before they're published, without affecting your live application.

Security best practices

• Never commit keys to source control—use environment variables
• Rotate keys periodically—delete old keys and create new ones
• Use descriptive names—makes it easier to identify and manage keys
• Revoke unused keys—if a key hasn't been used in months, delete it
• Separate environments—use different keys for staging and production
