### getConfirmedTransaction
Returns transaction details for a confirmed transaction
#### Parameters:
* `<string>` - transaction signature as base-58 encoded string
* `<string>` - (optional) encoding for the returned Transaction, either "json" or "binary". If not provided, the default encoding is JSON.
#### Results:
The result field will be an object with the following fields:
* `slot: <u64>` - the slot this transaction was processed in
* `transaction: <object|string>` - [Transaction](#transaction-structure) object, either in JSON format or base-58 encoded binary data, depending on encoding parameter
* `meta: <object>` - transaction status metadata object, containing `null` or:
* `err: <object | null>` - Error if transaction failed, null if transaction succeeded. [TransactionError definitions](https://github.com/solana-labs/solana/blob/master/sdk/src/transaction.rs#L14)
* `fee: <u64>` - fee this transaction was charged, as u64 integer
* `preBalances: <array>` - array of u64 account balances from before the transaction was processed
* `postBalances: <array>` - array of u64 account balances after the transaction was processed
* DEPRECATED: `status: <object>` - Transaction status
* `"Ok": <null>` - Transaction was successful
* `"Err": <ERR>` - Transaction failed with TransactionError
