Frequently Asked Questions

Why did my Kraken API key become invalid?
API keys can become invalid due to expiration (if you set a timeout), manual revocation for security reasons, account security changes, or if Kraken detected suspicious activity. Keys may also be automatically revoked if unused for extended periods.
How long do Kraken API keys last?
Kraken API keys don't have a built-in expiration date, but they can be configured with timeout periods for inactivity. Keys remain valid until manually deleted, revoked for security reasons, or if account credentials are changed.
Can I recover a deleted Kraken API private key?
No, Kraken private keys cannot be recovered once lost or if the API key is deleted. You must generate a new API key pair and update all applications using the old credentials.
What permissions should I set for my trading bot?
For basic trading bots, enable 'Query Funds', 'Query Open/Closed Orders', and 'Create & Modify Orders'. For read-only portfolio tracking, only enable query permissions. Never grant 'Withdraw Funds' permission unless absolutely necessary.
Is it safe to use Kraken API keys?
Yes, when configured properly. Use strong nonce window protection, set IP restrictions when possible, limit permissions to only what's needed, and never share your private key. Regularly rotate keys and monitor account activity for security.
