PrepareOrderCancellations​
Prepares cancellations for one or more orders.
Cancelling orders is a gasless alternative to on-chain cancellation exposed with CancelOrdersOnChain. For the orderbook to authenticate the cancellation, the creator of the orders must sign an EIP712 message containing the orderIds.

- OrderIdsof type- TArray<FString>- the ID's of the orders to attempt to cancel
See APIPrepareOrderCancellationsRequest for more information.

See APIPrepareOrderCancellations200Response for further information.
CancelOrders​
Cancels one or more orders.
Cancelling orders is a gasless alternative to on-chain cancellation exposed with CancelOrdersOnChain. Orders cancelled this way cannot be fulfilled and will be removed from the orderbook. If there is pending fulfillment data outstanding for the order, its cancellation will be pending until the fulfillment window has passed. PrepareOrderCancellations can be used to get the signable action that is signed to get the signature required for this call.
Method parameters
Request object containing parameters for cancelling orders:
- OrderIdsof type- TArray<FString>- the order IDs to attempt to cancel
- AccountAddressof type- FString- the address of the account cancelling the orders
- Signatureof type- FString- the signature obtained by signing the message obtained from- PrepareOrderCancellations
See APICancelOrdersRequest for more information.
