Kite Connect supports order modification and cancellation for open orders not yet fully executed:

Action	Endpoint
Modify order	PUT /orders/regular/:order_id
Cancel order	DELETE /orders/regular/:order_id
Modify cover/bracket	PUT /orders/co (or bo) /:order_id

Modify scenarios

What you can change	When
Quantity	Pending (not partially filled) orders
Price	Pending limit orders
Trigger price	Pending stop-loss orders
Validity	Pending orders
Order type	Pending orders (limited transitions)

Restrictions:

Cannot modify after partial fill (must cancel + re-place).
Cannot modify exchange / tradingsymbol / transaction_type (must cancel + re-place).

Cancel scenarios

Open pending orders (full cancellation).
Cannot cancel: fully executed, already cancelled, or rejected orders.

Python example

# Modify
kite.modify_order(
    variety="regular",
    order_id="240520000000123",
    price=2500.00
)

# Cancel
kite.cancel_order(
    variety="regular",
    order_id="240520000000124"
)
