Login to your Huobi account, hover your profile icon on top right and select API Management.
In Notes field type in what you want to call it, (ex. CoinStats Huobi), then click Create (make sure to assign Read-only permission)
Enter a verification code Huobi has sent to your email, then click Confirm.
You will see a screen like below with your Access and Secret keys.
Please make sure to copy/paste your Secret Key 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.
After that select Huobi from the list and paste your API Key and API Secret.
After clicking Submit you will see your Huobi portfolio synced with the CoinStats app.
