I needed to make shopify client in spring for my private project and couldnt find any examples on the internet , struggled a lot and finally made one . Sharing it because there might be some other people looking for one like I used to . This project uses https://github.com/graphql-java-generator to generate boilerplate code just from .graphqls file.Got my .graphqls by exporting SDL from Altair . Had to define some custom scalars in pom as well .

• First go to application.yml and change the url to your shopify app
  • How to create shopify app https://help.shopify.com/en/manual/apps/private-apps
• Next put your StoreFront API access token once again in the application.yml file
• After that use Maven clean compile and you are good to go
• Of course you would need to have made shopify private app with products on it for main application to work
• Use this to figure out how to write proper queries https://github.com/Shopify/storefront-api-learning-kit
