This section describes how typical web site code running on a web server uses the JSON-RPC API to keep track of customers' accounts.

  * Customer creates an account on the website: web server either assigns them a unique customer id number or uses their email address or other unique identifier, calls getaccountaddress "userid" and tells the customer to send to that address to fund their account.
  * Customer receives coins to fund their account: web server isn't involved.
  * Customer is shown their current balance: getbalance "userid" 6 to get their 'confirmed' balance, and subtracts it from getbalance "userid" 0 to get their 'unconfirmed' balance.
  * Show the customer an **itemized list** of transactions: listtransactions "userid"
  * Customer sends coins to another bitcoin address: sendfrom "userid" <address> <amount>
  * Customer transfers coins to another customer: move "userid1" "userid2" <amount>
  * You make a sale, paid for with bitcoins in the customer's account: move "userid" "" <amount> 6 "purchased item", and if it succeeds, send them the product.
  * Customer is charged a fee for use of the service: move "userid" "FEES" <amount> (using special accounts like "FEES" can make your application's logic much simpler)
  * Customer purchases bitcoins from you: move "AVAILABLE" "userid" <amount> (assuming the bitcoins you are selling are kept track of in an "AVAILABLE" account)
