> In HTTP idempotent is where the state of the server remains unchanged

No, it's not. That's closer to “safe” than “idempotent” (safe also implies idempotent, but not the other way around), but even then it is not quite right, because even safe methods are allowed to have side effects, but their is guidance about the kind and impact of side effects that it shouldn't have.
