I’ve been able to make a signature to place an order, but when I make a signature to cancel an order, I get an invalid signature message as a response, even though the same procedure is used to make the signature.
Has anyone tried to cancel all orders with the DELETE method? If so, have you had success making a valid signature?
One possible issue is body. What is body for canceling all orders?
Is it just {"profile_id": "key"} ?
