Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on September 03, 2026.
This Shopify update is categorized as API, Update, Hydrogen.
What changed
The Hydrogen developer preview adds new capabilities to the toolkit and extends the ways developers can build Shopify storefronts: Variant links: Links that name a variant, like the ones Shopify submits to a Google Shopping feed, now open on that variant instead of the product's default. Cart refresh: Reload the cart after your own code changes it, like a cart created on your server. Local HTTPS certificates: Hydrogen creates the certificates for Customer Account testing, so local login setup takes one command or none. To get started, visit the Hydrogen developer preview documentation. For a detailed breakdown of this release, read the full release notes.
