Updated function syntax on the segment query language
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on October 01, 2026.
This Shopify update is categorized as Action Required, API, Breaking API Change, GraphQL Admin API, 2026-10.
What changed
As of GraphQL Admin API version 2026-10, functions in the segment query language now use the operators MATCHES/NOT MATCHES instead of = true/= false. For example, the previous query shopify_email.opened() = true would now be represented as shopify_email.opened MATCHES (). The parameters for each function have also been expanded to use their own operators. For example, the query products_purchased(quantity: 5) = true would now be represented as products_purchased MATCHES (quantity = 5). This expands the functionality of parameters.
