I tried to get Shopify's purchase history

Added GraphQL and Flow apps to the store

Shopify's GraphQL is divided into Storeront and Admin. Software protection is implemented as a custom frontend with Shopify as the backend.

mutation {
   customerAccessTokenCreate(input: {email: "****", password: "*****"}) {
      customerAccessToken {
        accessToken
      }
   }
}

query {
   customer(customerAccessToken: "***") {
       orders(first: 250) {
           nodes {
              Financial Status
              customAttributes {
                 key
                 value
              }
              lineItems(first: 10) {
                 nodes {
                     variant {
                         product {
                            id
                            title
                         }
                      }
                  }
               }
           }
      }
}

I create an access token from an email address and password, but I don't know how to create an access token in the case of one-time token authentication.

Payment status of products from orders ( If payment has been made, PAID will be entered.

The Storefront API did not allow us to link the payment date and time from a GraphQL resolver, so we used the Flow applet.

Create a trigger when the payment status of an order changes to PAID, and set the date and time when the trigger occurs to the customAttributes field of Order.
