- order: POST /v1/sell/orders with the chosen asset_ids. set min_total_usd as a drift floor and external_id so retries never sell twice.
- trade: a csboard bot sends the steam offer. every order shows the bot profile and trade_offer_id, so your user can check the offer before accepting.
- settle: once accepted, the order waits out steam’s trade protection. the pending sum shows as incoming_hold in GET /v1/balance.
- get paid: the full quoted amount lands on your csboard balance and can be withdrawn right away.
