Authentication and default wallet

You should request your credentials to api@itbit.com, once you've got them you can configure the gem like this:

Itbit.client_key = 'your_client_key'
Itbit.secret = 'your_secret_key'
Itbit.user_id = 'your_user_id'

You can point the gem to itbit's sandbox like this:

Itbit.sandbox = true

Itbit gives you more than one 'wallet', which is a set of btc, usd, eur and sgd balances to use. Most of the time you'll probably end up using just one wallet, which can be configured like this:

Itbit.default_wallet_id = 'the-wallet-id-you-want-to-use'

All api calls that need a wallet accept one as an optional argument as well.

Get your wallets

ruby > Itbit::Wallet.all
=> { id: "3F2504E0-4F89-41D3-9A0C-0305E82C3301",
     name: "Wallet",
     balances: [
       { total_balance: "20.0".to_d,
         currency: :usd,
         available_balance: "10.0".to_d
       },
       { total_balance: "0.0".to_d,
         currency: :xbt,
         available_balance: "0.0".to_d
       },
       { total_balance: "0.0".to_d,
         currency: :eur,
         available_balance: "0.0".to_d
       },
       { total_balance: "0.0".to_d,
         currency: :sgd,
         available_balance: "0.0".to_d
       }
     ]
   }
