Kucoin API: (Error: {"code":"400004","msg":"Invalid KC-API-PASSPHRASE"})

If you get such an error, then you did not (or not correctly) follow step 2 of the instructions:

1. Log in into your KuCoin account and navigate to the API page (https://kucoin.com/account/api)
2. Enter 'cointracking' into the API Passphrase field
3. Create a new API key
4. DISABLE the trade permission for your new API key
5. Enter your Key and your Secret here

... and generate another key.

After clicking the "Create API" blue button, there will be a pop-up window (see the screenshot) where the user should type the API passphrase.

Then, he should pass the security verification by entering his / her Trading Password.
