Read account transactions history

Sometimes, developer may need to know user's transaction history. But in mixin network, there is no notification about transaction which is available in mixin messenger bots. To read user's transaction history , developer has to read all mixin network snapshots. If snapshot sender or receiver is created by developer, details of transaction will be available.
