# Resolve Hook Event • AI Agent SDK
> resolve_hook_event: Resolve an event id to a :class:`HookEvent`, or ``None`` if unknown.
# resolve\_hook\_event
Function
> This function is defined in the [**registry**](../modules/registry) module.
Resolve an event id to a :class:`HookEvent`, or `None` if unknown.
Accepts the enum itself, its canonical value (`"kanban_task_moved"`) and
its member name (`"KANBAN_TASK_MOVED"`). Emitting call sites historically
used the member name, so both spellings must reach the same subscribers.
