API Key: Your credential for the Bunny API. It identifies your account and authorizes requests. IMPORTANT: Without a valid API key, requests will be rejected with 401 Unauthorized.

​
How authentication works

All Bunny API endpoints use API key authentication only. Include the X-API-Key header in every request.

Where to send the key

All requests go to the same base URL (https://api.bunny.build/api/v1). The environment or plan is determined by the API key you use.

Authentication errors

The API returns HTTP 401 when:
  • The API key is missing from the header
  • The key is invalid
  • The key has been revoked

​
Getting an API key

  1. Sign in to the Bunny Dashboard
  2. Complete your profile if prompted
  3. Create an API token and copy it. It is shown only once
  4. Store the key in a secure place (e.g. environment variables or a secrets manager)

Security best practices

  • Store keys in environment variables or a secrets manager
  • Never commit API keys to version control or expose them in client-side code
  • Bunny will never ask for your key
  • Revoke any key that may have been compromised
