i have broker account. and i want to create sandbox account for my user as broker. so there is this
api: https://broker-api.sandbox.alpaca.markets//v1/accounts in which i can make account for my user.
but now i want to get/create trading api keys for this user (Apca-Api-Key-Id and Apca-Api-Secret-Key ).
i notice that if i want to manage user account i have to use account_id in broker api to make orders or cancel orders , list positions etc… but i want to get those api keys. is that possible?
