Introducing the new Collection Sources API
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on July 01, 2026.
This Shopify update is categorized as API, New, GraphQL Admin API.
What changed
The new Collection Sources API gives partners a more flexible way to build merchandising experiences in Shopify. In GraphQL Admin API 2026-07, collections can combine multiple sources, target specific variants, reference other collections, and include shareable sources authored by apps. For partners, this creates a new way to build directly into Shopify's native merchandising model. For most of Shopify's history, collections fit into one of two models: custom collections, where merchants manually chose products, or smart collections, where conditions populated products automatically. That model helped millions of merchants merchandise their catalogs, but it also forced tradeoffs.
