  2. Select API keys.
  3. Confirm the current environment.
  4. Copy the key you need.
  5. Store secret keys only on your server.

Rotate a key

Rotate a key if it may have been exposed or when your security process requires it. Update your integration before disabling an old key.

  • Do not share secret keys in chat, email, screenshots, or client-side code.
  • Use separate keys for sandbox and production.
  • Remove unused keys.
