`GET /banking/bank-transactions/{id}`

Read-only: Reads and returns; changes nothing.

Retrieves a bank transaction. A bank transaction is a single movement of funds on a bank account. Use the transaction's id, not its bankTransactionNumber. There is no direction field: a negative amount is money out and a positive amount is money in.
