Accounts allow you to separate funds on your escrow. You may want to do this so that certain funds never mix for accounting or business reasons. Every customer starts off with one account, called the default account. A customer can create any number of accounts. Each account must have a unique "key" often referred to as the "accountKey". Once set, this key cannot be updated. Once an account is created, it cannot be deleted. Funds are withdrawn to a customer's bank account per account. So, if you have funds spread over several accounts, several withdrawals will need to be created to withdrawal all of the funds.
