Shopify deprecates their APIs once every 6 months and it is a situation of anxiety for our development team.
Because in case there is still a call site which is making calls to deprecated APIs, your shopify app can get delisted.
Finding call sites for deprecated APIs can sometimes become challenging specially in large code bases involving multiple services.
In case a developer made a postman call to a deprecated API I guess that would still count as an invalid call and can lead to delisting.
In Shopify's defence they do start to give a warning about deprecated APIs way before but taking a strong action like delisting the app feels weird.
Maybe just making the existing APIs return an error citing deprecation would have been better ?
