Stripe "No such token: " error

my stripe account is configured with test. and using test keys into my laravel application.

While posting, i am creating new stripe user if not exist like this,

Stripe::setApiKey(Config::get('constants.features.stripe.secret'));
$token = $input['_token']; 

$customer = Stripe_Customer::create(array(
            "description" => "#{$user->id} / {$user->username} / {$user->email}",
            "source" => $token,
            "email" => $user->email
        ));

And creating charge like this,

$charge = Stripe_Charge::create(array(
                "amount" => '5000',
                "currency" => "gbp",
                "customer" => $customer->id,
                "description" => 'description',
                "statement_descriptor" => strtoupper("test desc")
            ));

But it return error Stripe_InvalidRequestError No such token:
