1. create a presentation

    function createPresentation($title) {
        $presentation = new Google_Service_Slides_Presentation(array(
            'title' => $title
        ));
        $presentation = $this->slidesService->presentations->create($presentation);
        $presentationLastId = $presentation->presentationId;

        return $presentationLastId;
    }

2. append a slide

    protected function createSlideRequest($presentationId, $slideId, $data = array())
    {
        $requests = array();
        $requests[] = new Google_Service_Slides_Request(array(
            'createSlide' => array (
                'objectId' => $slideId,
                'slideLayoutReference' => array ('predefinedLayout' => 'BLANK')
             ),
        ));

        $batchUpdateRequest = new Google_Service_Slides_BatchUpdatePresentationRequest(array(
            'requests' => $requests
        ));

        $response = $this->slidesService->presentations->batchUpdate($presentationId, $batchUpdateRequest);
