get https://sandbox-api.helix.q2.com/transaction/getByTag//
Retrieve a list of transactions related to the given customerId and tag. The list is ordered by settledDate, descending.
The output is a list because multiple transaction objects may be tied to a given
transactionId. This is because a single call to transfer/create can result in multiple transactions, e.g., a fee is applied (such as an NSF during NACHA file processing). A fee is considered a separate, but instrinsically related, transaction.
