API Reference

Cancel Order Signature

The method Create Order Cancellation Signature allows user to create cancellation signatures for the provided orders. Similar to creating orders, signatures are used to validate the authenticity of the request since the order must be cancelled off-chain on the orderbook before being cancelled on-chain.

Sub Accounts: If trading as a sub account, set the maker field to the address of the parent account. Read more about Sub Accounts here.

The method takes the following input parameters:

  • interface OrderCancelSignatureRequest {
      symbol: MarketSymbol; // symbol of market of orders to be cancelled
      hashes: string[]; // hash of the orders to be cancelled
      parentAddress?: string // (optional) specify parent account if trading as a sub account
    }
    
    class OrderCancelSignatureRequest(TypedDict):
      symbol: MARKET_SYMBOLS # symbol of market of orders to be cancelled
      hashes: list  # hash of the orders to be cancelled
      parentAddress: str # (optional) should only be provided by a sub account
    

The order hash parameter is returned as part of the post order response or can be obtained via the get order routes.
