Login to your Liquid account, hover your profile icon on top right and select Application Settings.
Click Create API Token from API Tokens menu.
Enable Read access on Accounts and Orders, input your 2FA code if enabled and click Create Token.
You will see a screen like below with your Token ID and Token Secret.
Please make sure to copy/paste your Token Secret code to a safe place, as it will only be displayed at the time it is created. If you lose this key, you will need to delete your API and set up a new one.
Now go to CoinStats app Portfolio tab, swipe far to the right and click Connect Exchange.
Select Liquid from the list and paste your Token ID and Secret.
After clicking Submit you will see your Liquid portfolio synced with the CoinStats app.
