如何将Authorize.net API导入Wordpress？

我正在尝试将Authorize.net支付表单集成到我的Wordpress站点。这不是一个产品页面，所以我不只是使用标准的WooCommerce插件。相反，我希望集成自己的代码，使用AcceptUI付款表单，然后处理响应。我已经阅读了所有的API代码并理解了，但是如何将SDK引入到我的Wordpress环境中呢！？！例如，我已经创建了我的payment nonce并想调用下面的代码，但是如何将CreateTransactionController类引入到我的Wordpress结构中呢

如果我只能像下面的代码一样提交付款，那就太完美了。我可以处理响应，将用户引导到签出过程中的下一个部分，最后将订单信息提交给Woocommerce进行记录

任何帮助都将不胜感激！先谢谢你
