Addfee is a shortcut and safeguard for adding the required additional factoshis to covert the fee. The fee is displayed in the returned transaction after each step, but addfee should be used instead of manually adding the additional input. This will help to prevent overpaying.

Addfee will complain if your inputs and outputs do not match up. For example, in the steps above we added the inputs first. This was done intentionally to show a case of overpaying. Obviously, no one wants to overpay for a transaction, so addfee has returned an error and the message: ‘Inputs and outputs don’t add up’. This is because we have 2,000,000,000 factoshis as input and only 1,000,000,000 + 10,000 as output. Let’s correct the input by doing 'add-input’, and putting 1000010000 as the amount for the address.

This will retrieve a transaction by the given TxID. This call is the fastest way to retrieve a transaction, but it will not display the height of the transaction. If a height is in the response, it will be 0. To retrieve the height of a transaction, use the 'By Address’ method
