Seamless collection synchronization with updated Shopify Collection APIs

Improvement

Shopify updated collections to support variant-level targeting, allowing specific product variants, like a single color, material, or size run, to be included instead of whole products.

Boost's collection sync was built around whole products, so without an update, these new collections would show up blank or point shoppers to the wrong product version. But you don’t need to worry, as we closed that gap so your storefront keeps working the way you expect, no matter how Shopify changes underneath it.

What changed

Four things, all live now:

  • Accurate sync. Boost's sync process now reads both the old and new Shopify collection formats, so every collection you've already built keeps working exactly as it does today, and new variant-level collections sync in correctly from the start.
  • The right product card. When a shopper browses a variant-level collection, Boost shows the card for the matching variant, including its own image, not a generic parent product.
  • Working filters. Filtering inside variant-level collections now returns the results shoppers expect, so narrowing down further doesn't dead-end or drop them back into the full catalog.
  • Variant collection with Variant Display feature: On a variant collection page, the split variant products that have been added to that collection will be displayed.

What this means for you

You can now build more precise collections in Shopify by color, material, size, or any variant attribute, and trust that Boost will display and filter them correctly on your storefront. If you already publish variant-level collections in Shopify, or you've been waiting on this before you do, they'll work as soon as they're live in your store.

If you have questions or need help with anything, open a live chat in your Boost dashboard, and we’ll resolve it right away.

What’s coming next

Nested collections, where one collection inherits its products from another, are part of the same Shopify update and are still being explored on our side, along with how they interact with Multi-Collections Filter. We'll share an update once we've scoped that work.

Shopify's new Collections API enables variant-level collections, such as displaying only red items in a Valentine's Red collection. Boost now automatically recognizes and syncs these collections, displaying the exact matching variant product card and enabling proper filtering.
