SDK v7.2.8 is injecting unsupported fields into the put object for /spot/price_orders

[sambaTux]

Hi everyone,

I have this issue with the official Gate.io python SDK:

Environment:

• Python: 3.x (Linux/Windows)

• gate-api: 7.2.8

• Endpoint: SpotApi.create_spot_price_triggered_order

from gate_api import Configuration, ApiClient, SpotApi, SpotPricePutOrder, SpotPriceTrigger, SpotPriceTriggeredOrder

configuration = Configuration(
    host="https://api.gateio.ws/api/v4",
    key=api_key,
    secret=api_secret,
)
api_client = ApiClient(configuration)
spot_api   = SpotApi(api_client)



def place_stop_loss(symbol, base_amount, entry_price, side, sl_pct):
    if side.lower() == "buy":
        trigger_price = round(entry_price * (1 - sl_pct), 6)
        order_side    = "sell"
        trigger_rule  = "<="
    elif side.lower() == "sell":
        trigger_price = round(entry_price * (1 + sl_pct), 6)
        order_side    = "buy"
        trigger_rule  = ">="
    else:
        return None

    put_order = SpotPricePutOrder(
        type="market",
        side=order_side,
        price="",
        amount=str(base_amount),
    )

    trigger = SpotPriceTrigger(
        price=str(trigger_price),
        rule=trigger_rule,
        expiration=7 * 24 * 60 * 60,
    )

    price_triggered_order = SpotPriceTriggeredOrder(
        market=symbol,
        trigger=trigger,
        put=put_order,
    )

    print("SpotPricePutOrder payload:", put_order.to_dict())
    print("SpotPriceTriggeredOrder payload:", price_triggered_order.to_dict())

    created = spot_api.create_spot_price_triggered_order(price_triggered_order)
    print("Created stop-loss:", created)
    return created.id

Example call:

place_stop_loss(
    symbol="DOGE3L_USDT",
    base_amount=10530.93,
    entry_price=0.002279,
    side="Buy",
    sl_pct=0.10,
)

Log output

SpotPricePutOrder payload: {'type': 'market', 'side': 'sell', 'price': '', 'amount': '10530.93', 'account': 'normal', 'time_in_force': 'gtc', 'auto_borrow': False, 'auto_repay': False, 'text': None}
SpotPriceTriggeredOrder payload: {'trigger': {'price': '0.002051', 'rule': '<=', 'expiration': 604800}, 'put': {'type': 'market', 'side': 'sell', 'price': '', 'amount': '10530.93', 'account': 'normal', 'time_in_force': 'gtc', 'auto_borrow': False, 'auto_repay': False, 'text': None}, 'id': None, 'user': None, 'market': 'DOGE3L_USDT', 'ctime': None, 'ftime': None, 'fired_order_id': None, 'status': None, 'reason': None}

HTTP 400 response:
{"label":"INVALID_PARAM_VALUE","message":"invalid argument: put.time_in_force"}

Conclusion
So it looks like gate-api 7.2.8 (had the same issue with v.7.1.8) is serializing extra fields (time_in_force, account, etc.) into put for SpotPriceTriggeredOrder, but /spot/price_orders rejects put.time_in_force with INVALID_PARAM_VALUE

Thank you very much for your help.
