The table below shows the parameter you'll need to POST and the format of a successful response. Each user is associated with one or more accounts and each user has a default account. You pass just the username and password to get a token for the user's default account or you can optionally pass a valid account_id to get a token that is associated with an account other than the user's default account. To get the account_id for accounts the user has access to you can call the user.getAccounts method.
