+shopify的APP应用
+根据您的应用程序的用途以及发行或销售方式，首先需要选择要构建的应用程序类型。创建应用后，无法更改应用类型，因此请确保您了解每种类型的不同功能和要求。共有三种应用类型：
+- 公开应用
+- 自定义应用
+- 私人应用
+
+公开应用
+公开应用程序适用于希望将其应用程序分发给许多商人的开发人员。这些是公共应用程序的关键功能：
+- 它们可以安装在多个Shopify商店中
+- 他们必须通过Shopify的应用批准流程
+- 您可以在Shopify App Store中出售它们
+- 他们使用OAuth 2.0管理身份验证
+- 它们是在您的合作伙伴信息中心中创建和管理的
+- 他们可以使用Shopify App Bridge在Shopify管理员中显示为嵌入式应用程序
+- 他们可以使用应用程序扩展来扩展Shopify管理界面
+- 他们必须将某些客户数据与Shopify同步，如API使用条款中所述
+教程：使用OAuth对公共应用进行身份验证
+自定义应用
+自定义应用程序适用于开发人员构建针对单个商家的应用程序。这些是自定义应用程序的关键功能：
+- 它们可以安装在单个Shopify商店中
+- 他们没有通过Shopify的应用批准流程
+- 您不能在Shopify App Store中出售它们
+- 您不能使用Billing API向商家收费
+- 他们使用OAuth 2.0管理身份验证
+- 它们是在您的合作伙伴信息中心中创建和管理的
+- 他们可以使用Shopify App Bridge在Shopify管理员中显示为嵌入式应用程序
+- 他们可以使用应用程序扩展来扩展Shopify管理界面
+教程：使用OAuth验证自定义应用
+私人应用
+开发人员仍然可以创建私人应用程序，但是推荐使用自定义应用程序。
+私人应用程序是指开发人员为商家开发的应用程序，而这些应用程序具有特定要求，而自定义应用程序无法满足这些要求。这些是私人应用程序的关键功能：
+- 它们是为单个Shopify商店或一小部分客户创建的
+- 他们没有通过Shopify的应用批准流程
+- 您不能在Shopify App Store中出售它们
+- 使用基本HTTP身份验证管理身份验证
+- 它们是在商家的Shopify管理员中创建和管理的
+教程：使用Shopify管理员对私人应用进行身份验证
