here's my code

public function update(UpdateSubscriptionRequest $request)
    {
        $data  = $request->validated();
        $user  = $request->user;

        $user->subscription()->swap($data['price_id']);

        return $this->respondOk(SubscribtionResource::make($user->subscription()->asPaddleSubscription()) , "Subscribtion swapped successfully");
    }
