Before we start with API keys.
1. Kraken has introduced a new Kraken Pro version that offers the same API keys creation feature. So to create new API keys, you need to switch to the Kraken Classic or Kraken Pro:
If you stay just on Kraken and try to create API keys, you will still be prompted to move to Kraken Pro:
2. The process of the API keys creation on Kraken Classic has not changed. Here in this article, you will be given screenshots of both Classic and Pro versions.

2. Switch to Kraken Pro

Frequently Asked Questions
Why can’t I see or trade with all of my funds on Kraken?
If your available balance in 3Commas looks lower than expected, or you see errors like “Unable to load available balance” or “EAPI: Invalid nonce”, here are the most common causes and fixes:
1. Margin Mode is Enabled
Please check if Margin trading mode is enabled on your Kraken account. Assets used as collateral in margin trades are locked and will not appear as available via the API.
Learn more here:
2. Kraken Earn is Enabled
Assets in your spot account may be earning yield via Kraken’s Earn feature. These assets appear available on Kraken, but are hidden from API access, so 3Commas cannot see them.
To fix this, disable the Earn feature for those assets in your Kraken account.
3. Nonce Sync Issues (EAPI errors)
A misconfigured Nonce window may cause API sync failures.
Common errors:
EAPI: Invalid nonce
Unable to load available balance
Go to your Kraken API key settings and set the Nonce window to 2000000 (2 million). Save and reconnect the API key in 3Commas.

PRO:
Why can’t I find DOGE pairs when creating a bot?
Kraken uses a different asset code for DOGE in their API — it’s listed as XDG. To find DOGE pairs on 3Commas, simply search using XDG instead of DOGE.
I’m seeing “HTTP 429” or “Rate limit exceeded” errors — what can I do?
Kraken enforces strict API rate limits. These can be triggered when:
You have multi-pair bots with many active orders
Several trades open simultaneously, each submitting orders at once
If your Kraken account is Level 2 or lower, these errors are more likely.
Solution: Upgrade to Kraken Level 3 KYC to increase your API rate limit.

Also, enabling IP Whitelisting may reduce connection issues — see setup in the main article above.
