There doesn t seem to be an `on cancelled` hook but you should be able to access the run state as described in this example <https discourse prefect io t how to take action on a state change of a task run task level state handler 82> It seems that this only applis to tasks though not flows Perhaps it might work if you submit your flow as a subflow and access the future from the parent flow

Filip Panovski · Answer

You can also return the flow state directly using `return state=True` <https docs prefect io latest concepts states return prefect state>
