Date range for transaction history

Please clarify the following questions for “Sing in with Coinbase” List Transaction API:

  1. what is available date range? In other words what is the earliest transaction available?
  2. is there is a way to get only transactions that occurred after a certain date? If so, how to communicate such a date in the API request?
  3. how to get old transactions such as from 3 - 5 year ago?

Best regards
