Cancel Order

Cancel single, multiple, or all open orders

All cancel endpoints require L2 authentication. The response always includes canceled (list of cancelled order IDs) and not_canceled (map of order IDs to failure reasons).

Cancel a Single Order

```typescript TypeScript theme={null} const resp = await client.cancelOrder("0xb816482a..."); console.log(resp); // { canceled: ["0xb816482a..."], not_canceled: {} } ```

resp = client.cancel(order_id="0xb816482a...")
print(resp)
# {"canceled": ["0xb816482a..."], "not_canceled": {}}

let resp = client.cancel_order("0xb816482a...").await?;
println!("{:?}", resp);
// CancelOrdersResponse { canceled: ["0xb816482a..."], not_canceled: {} }

  -H "POLY_TIMESTAMP: ..." \
  -H "POLY_API_KEY: ..." \
  -H "POLY_PASSPHRASE: ..." \
  -d '{"orderID": "0xb816482a..."}'

Cancel Multiple Orders

```typescript TypeScript theme={null} const resp = await client.cancelOrders(["0xb816482a...", "0xc927593b..."]); ```

resp = client.cancel_orders([
    "0xb816482a...",
    "0xc927593b...",
])

let resp = client.cancel_orders(&["0xb816482a...", "0xc927593b..."]).await?;

  -H "Content-Type: application/json" \

  -H "POLY_API_KEY: ..." \
  -H "POLY_PASSPHRASE: ..." \
  -d '["0xb816482a...", "0xc927593b..."]'

Cancel All Orders

Cancel every open order across all markets:

```typescript TypeScript theme={null} const resp = await client.cancelAll(); ```

resp = client.cancel_all()

let resp = client.cancel_all_orders().await?;

curl -X DELETE "https://clob.polymarket.com/cancel-all" \
  -H "POLY_ADDRESS: ..." \
  -H "POLY_SIGNATURE: ..." \
  -H "POLY_TIMESTAMP: ..." \
  -H "POLY_API_KEY: ..." \
  -H "POLY_PASSPHRASE: ..."

Cancel by Market

Cancel all orders for a specific market, optionally filtered to a single token. Both market and asset_id are optional — omit both to cancel all orders.

```typescript TypeScript theme={null} const resp = await client.cancelMarketOrders({ market: "0xbd31dc8a...", // optional: condition ID asset_id: "52114319501245...", // optional: specific token }); ```

resp = client.cancel_market_orders(
    market="0xbd31dc8a...",
    asset_id="52114319501245...",  # optional
)

use polymarket_client_sdk::clob::types::request::CancelMarketOrderRequest;

let request = CancelMarketOrderRequest::builder()
    .market("0xbd31dc8a...".parse()?)
    .asset_id("52114319501245...".parse()?)
    .build();
let resp = client.cancel_market_orders(&request).await?;

curl -X DELETE "https://clob.polymarket.com/cancel-market-orders" \
  -H "Content-Type: application/json" \
  -H "POLY_ADDRESS: ..." \
  -H "POLY_SIGNATURE: ..." \
  -H "POLY_TIMESTAMP: ..." \
  -H "POLY_API_KEY: ..." \
  -H "POLY_PASSPHRASE: ..." \
  -d '{"market": "0xbd31dc8a...", "asset_id": "52114319501245..."}'

Onchain Cancellation

If the API is unavailable, you can cancel orders directly on the Exchange contract by calling cancelOrder(Order order) onchain. Pass the full order struct that was signed when placing the order.

Use the CTFExchange or NegRiskCTFExchange contract depending on the market type. See Contract Addresses for addresses.

This is a fallback mechanism — API cancellation is instant while onchain cancellation requires a transaction.

Querying Orders

Get a Single Order

```typescript TypeScript theme={null} const order = await client.getOrder("0xb816482a..."); console.log(order.status, order.size_matched); ```

order = client.get_order("0xb816482a...")
print(order["status"], order["size_matched"])

let order = client.order("0xb816482a...").await?;
println!("{:?} {}", order.status, order.size_matched);

Get Open Orders

Retrieve all open orders, optionally filtered by market or token:

```typescript TypeScript theme={null} // All open orders const orders = await client.getOpenOrders();

// Filtered by market const marketOrders = await client.getOpenOrders({ market: "0xbd31dc8a...", });

// Filtered by token const tokenOrders = await client.getOpenOrders({ asset_id: "52114319501245...", });


```python Python theme={null}
from py_clob_client.clob_types import OpenOrderParams

# All open orders
orders = client.get_orders()

# Filtered by market
market_orders = client.get_orders(
    OpenOrderParams(market="0xbd31dc8a...")
)

use polymarket_client_sdk::clob::types::request::OrdersRequest;

// All open orders
let orders = client.orders(&OrdersRequest::default(), None).await?;

// Filtered by market
let request = OrdersRequest::builder()
    .market("0xbd31dc8a...".parse()?)
    .build();
let market_orders = client.orders(&request, None).await?;

OpenOrder Object

Field	Type	Description
`id`	string	Order ID
`status`	string	Current order status
`market`	string	Condition ID
`asset_id`	string	Token ID
`side`	string	`BUY` or `SELL`
`original_size`	string	Size at placement
`size_matched`	string	Amount filled
`price`	string	Limit price
`outcome`	string	Human-readable outcome (e.g., "Yes", "No")
`order_type`	string	Order type (GTC, GTD, FOK, FAK)
`maker_address`	string	Funder address
`owner`	string	API key of the order owner
`associate_trades`	string[]	Trade IDs this order has been included in
`expiration`	string	Unix expiration timestamp (`0` if none)
`created_at`	string	Unix creation timestamp

Trade History

When an order is matched, it creates a trade. Trades progress through these statuses:

Status	Terminal	Description
`MATCHED`	No	Matched and sent for onchain submission
`MINED`	No	Mined on the chain, no finality yet
`CONFIRMED`	Yes	Achieved finality — trade successful
`RETRYING`	No	Transaction failed — being retried
`FAILED`	Yes	Failed permanently

```typescript TypeScript theme={null} // All trades const trades = await client.getTrades();

// Filtered by market const marketTrades = await client.getTrades({ market: "0xbd31dc8a...", });


```python Python theme={null}
from py_clob_client.clob_types import TradeParams

trades = client.get_trades()

market_trades = client.get_trades(
    TradeParams(market="0xbd31dc8a...")
)

use polymarket_client_sdk::clob::types::request::TradesRequest;

// All trades
let trades = client.trades(&TradesRequest::default(), None).await?;

// Filtered by market
let request = TradesRequest::builder()
    .market("0xbd31dc8a...".parse()?)
    .build();
let market_trades = client.trades(&request, None).await?;

Additional filter parameters: id, maker_address, asset_id, before, after.

The Rust SDK uses cursor-based pagination via the next_cursor parameter:

```typescript TypeScript theme={null} const page = await client.getTradesPaginated({ market: "0xbd31dc8a..." }); console.log(page.trades, page.count); // trades array + total count ```

page = client.get_trades_paginated(TradeParams(market="0xbd31dc8a..."))

// First page
let page = client.trades(&request, None).await?;
println!("{} trades, cursor: {}", page.data.len(), page.next_cursor);

// Next page
let page2 = client.trades(&request, Some(page.next_cursor)).await?;

Trade Object

Field	Type	Description
`id`	string	Trade ID
`taker_order_id`	string	Taker order hash
`market`	string	Condition ID
`asset_id`	string	Token ID
`side`	string	`BUY` or `SELL`
`size`	string	Trade size
`price`	string	Execution price
`fee_rate_bps`	string	Fee rate in basis points
`status`	string	Trade status (see table above)
`match_time`	string	Unix timestamp when matched
`last_update`	string	Unix timestamp of last status change
`outcome`	string	Human-readable outcome (e.g., "Yes")
`maker_address`	string	Maker's funder address
`owner`	string	API key of the trade owner
`transaction_hash`	string	Onchain transaction hash
`bucket_index`	number	Index for trade reconciliation
`trader_side`	string	`TAKER` or `MAKER`
`maker_orders`	MakerOrder[]	Maker orders that filled this trade

A single trade can be split across multiple onchain transactions due to gas limits. Use `bucket_index` and `match_time` to reconcile related transactions back to a single logical trade.

Order Scoring

Check if your resting orders are eligible for maker rebates scoring:

```typescript TypeScript theme={null} // Single order const scoring = await client.isOrderScoring({ orderId: "0x..." });

// Multiple orders const batch = await client.areOrdersScoring({ orderIds: ["0x...", "0x..."], });


```python Python theme={null}
from py_clob_client.clob_types import OrderScoringParams, OrdersScoringParams

scoring = client.is_order_scoring(
    OrderScoringParams(orderId="0x...")
)

batch = client.are_orders_scoring(
    OrdersScoringParams(orderIds=["0x...", "0x..."])
)

// Single order
let scoring = client.is_order_scoring("0x...").await?;

// Multiple orders
let batch = client.are_orders_scoring(&["0x...", "0x..."]).await?;
