use click\models\Payments;
class MyPayments extends Payments{
    ...
}
$model = new MyPayments();

    'temporary' => 1
]);

Verify card token

2) Overwrite the some methods over the Payments

use click\models\Payments;
class MyPayments extends Payments{
    /**
     * @param data array
     * @return response \GuzzleHttp\Client
     */
    public function on_invoice_creating($data){
        ...
        $response = $this->client->request('POST', 'invoice/create', [
            ...
        ]);
        ...
        return $response;
    }
    /**
     * @param request array
     * @param response \GuzzleHttp\Client object
     * @param token string
     * @return response array|null
     */
    public function on_invoice_created($request, $response, $token){
        ...
        if($response->getStatusCode() == 200){
            $result = (array)json_decode((string) $response->getBody());
            ...
            $this->model->update_by_token($token, [
                ...
            ]);
            ...
        }
        ...
        return $result;
    }
}
