If you are an account Admin or Campaign Manager (with wallet permissions), you can view a full list of your account's transactions by visiting your Wallet.
From the 'Welcome' page, there are two ways to access your wallet:
Click “Manage Wallet” in the bottom left box on your homescreen.
Click “Wallet” at the bottom of the left-hand navigation menu.
Once you have reached your wallet, the transaction history should open by default, or you can navigate to it by clicking “Transaction History” under your account balance.
