get https://api.prime.coinbase.com/v1/portfolios//orders
List historical orders for a given portfolio. This endpoint returns a payload with a default limit of 100 if not specified by the user. The maximum allowed limit is 3000.
Caution: Currently, you cannot query open orders with this endpoint: use List Open Orders if you have less than 1000 open orders, otherwise use Websocket API, or FIX API to stream open orders.
