In the 2022-04 API version release, Shopify is introducing a Segmentation API for the GraphQL Admin. The API helps app partners support merchants that want to target specific customer groups for marketing, analytics, and reporting. Saved searches and Discount Eligibility based on saved searches, will be deprecated in favor of the Segmentation API.
If your app uses saved searches, then you need to migrate your app to support segments. Learn more about Segmentation in our developer documentation or visit our API forum for questions.
