Note your BitNZ Username, and visit your View/Edit API Keys page.
Under Create New Key, make sure that you do not have the Can trade or Can withdraw permissions enabled,
and click Create New Key.
Copy and paste the API Key and API Secret, along with your BitNZ Username into the
"Add new Exchange" form, and click "Add account".
Is it safe to provide CryptFolio a BitNZ API key?
You need to make sure that the API key does not have the Can trade or Can withdraw permissions. This should
mean that the API key can only be used to retrieve account status, and it should not be possible
to perform trades or withdraw funds using that key.
Your BitNZ username, keys and secrets will never be displayed on the CryptFolio site, even if you have logged in.
Through the BitNZ interface you can delete an API key at any time by clicking Delete.
