1、参考：https://shopify.dev/api/admin-graphql#authentication ，所有 GraphQL Admin API 查询都需要有效的 Shopify 访问令牌。
2、打开后台 – 应用 – 开发应用 – 创建自定义应用。如图1
图1
3、输入应用名称，选择应用开发者，创建应用。如图2
图2
4、配置后台 API 范围。如图3
图3
5、应用开发 – Shopify 访问令牌 – 配置 – 后台 API 集成 – 选择访问范围 – 保存。如图4
图4
6、API 凭据，您还没有任何访问令牌。若要获取后台 API 访问令牌，请安装应用。安装应用。如图5
图5
7、API 凭据 – 后台 API 访问令牌。为保护您的数据，您的后台 API 令牌只能显示一次。请复制您的后台 API 访问令牌并将其保存在安全位置。如图6
图6
8、参考：https://shopify.dev/api/admin-graphql#endpoints 。通过向端点发送 POST HTTP 请求来执行 GraphQL 查询。获取最近添加的三个产品的 ID 和标题。在 Altair GraphQL Client 中，新开窗口，输入网址：https://fanxiapp-wangqiang.myshopify.com/admin/api/2022-01/graphql.json ，弹出登录框，如图7
图7
9、设置 Headers ，Content-Type: application/graphql，X-Shopify-Access-Token: {access_token}。如图8
图8
10、设置查询后，响应 404。查看网络请求，先是 301 跳转至 /admin/auth/login，然后 302 跳转至 /admin。如图9
图9
{
products(first: 3) {
edges {
node {
id
title
}
}
}
}
11、但是在 Git Bash 执行查询，响应 200。如图10

12、参考： https://shopify.dev/api/admin/getting-started#use-curl 。如果您使用的是 HTTP 客户端，例如 Postman 或 Insomnia，则必须将 Content-Type 设置为 application/json 而不是 application/graphql。重新设置 Headers ，Content-Type: application/json。仍然响应 404。当切换为一个正式的商店后，响应 200。如图11

16、在 Postman 、Git Bash 中，试用期与正式皆可用。而在 Altair GraphQL Client，试用期不可用，仅正式可用。初步怀疑与在试用期网址调用时手动输入帐号密码登录有关系。不应手动登录。
