I am developing an iOS application in which there is one portion where the user can purchase the products. The products are being shown from Shopify store through MobileBuySDK iOS using GraphQL. To use the application, the user needs to signup in our app and then he can access other things . Now the issue is we are not creating user on shopify, so is there any way that we can get the order history of the user from shopify without creating the user on shopify? I have read about the multipass login but it is available on shopifyPlus and its pricing is way high. so is there any other way.
