兼容性
在某些情况下，动态结账按钮可能不适合您的在线商店。在您的在线商店中显示动态结账按钮之前，请考虑它们与以下功能的兼容性：
应用
购物车属性
产品、付款设置和按钮文字
应用
动态结账按钮可能与某些应用冲突。
如果您使用以下任意一种应用，那么动态结账按钮可能与您的在线商店不兼容：
Currency converter
与购物车互相影响的应用
将客户转至外部结账的应用
购物车属性
动态结账按钮不支持购物车属性。购物车属性是自定义表单字段，可用于在购物车页面上收集客户的其他信息。
购物车属性的示例包括购物车页面的以下添加项：
条款和条件复选框
礼品包装选项
配送日期选择器
如果您依赖于购物车属性，动态结账按钮则不适合您的在线商店。
产品、付款设置和按钮文字
在您的在线商店中显示动态结账按钮之前，请考虑以下细节：
动态结账按钮只能用于购买某种产品的单个多属性。但是，如果您在产品页面上显示数量选择器，则客户可以购买多个该产品。例如，顾客可以使用动态结账按钮购买三个浅绿色烘焙杯，但不能购买一个浅绿色烘焙杯和一个紫色烘焙杯。除非您的在线商店收到一种产品的多个订单，否则动态结账按钮并不能为您的销量带来好处。
如果您的收款设置中未启用第三方快捷结账方式，则动态结账按钮的无品牌版本将是唯一显示的版本。
动态结账按钮的无品牌版本显示立即购买文本。如果您的 Add to cart（添加到购物车）按钮显示立即购买或其他自定义文本，那么这可能会使客户感到困惑。
更新模板以使用动态结账按钮
动态结账按钮适用于 Shopify 模板商店中所有最新版本的模板。如果您使用的是旧版模板，则可以更新您的模板以使用动态结账按钮。如果您不想更新模板，则可以编辑您的模板代码。

Compatibility
There are a few cases where dynamic checkout buttons might not be suitable for your online store. Before you show dynamic checkout buttons on your online store, consider their compatibility with the following features:
Apps
Cart attributes
Products, payment settings, and button text
Apps
Dynamic checkout buttons might conflict with certain apps.
If you use any of the following kinds of apps, then dynamic checkout buttons might not be compatible with your online store:
Currency converters
Apps that interact with the cart
Apps that take customers to an external checkout
Cart attributes
Dynamic checkout buttons don't support cart attributes. Cart attributes are custom form fields that you can use to collect additional information from your customers on the cart page.
Examples of cart attributes include the following additions to the cart page:
Terms and conditions checkboxes
Gift-wrapping options
Delivery date pickers
If you rely on cart attributes, then dynamic checkout buttons aren't suitable for your online store.
Products, payment settings, and button text
Before you show dynamic checkout buttons on your online store, consider the following details:
Dynamic checkout buttons can only be used to buy a single variant of a product. However, if you show a quantity selector on the product page, then customers can buy more than one of that product. For example, a customer can use a dynamic checkout button to buy three baking cups in aqua, but not to buy one in aqua and one in purple. Unless your online store receives many orders for one kind of product, then dynamic checkout buttons might not benefit your sales.
If you don't have a third-party accelerated checkout method enabled in your payment settings, then the unbranded version of the dynamic checkout button is the only version that will show.
The unbranded version of the dynamic checkout button shows Buy it now text. If your Add to cart button shows Buy it now or other custom text, then this might confuse customers.
Update your theme to use dynamic checkout buttons
Dynamic checkout buttons are available on all current versions of the themes in the Shopify Theme Store. If you're using an older version of a theme, then you can update your theme to use dynamic checkout buttons. If you don't want to update your theme, then you can edit your theme code.
