I’d like to request support for publishing variant fixed bundles on custom storefronts, similar to how product fixed bundles are supported today.
As per the current bundle publishing documentation, publishing is only supported for product fixed bundles:
Publishing is only supported for product fixed bundles. You can’t publish variant fixed bundles.
Shopify currently supports two types of fixed bundles:
Product fixed bundles
Configured at the product level, where bundle relationships are defined using products and option values.
Variant fixed bundles
Configured at the variant level, where bundle relationships are defined using specific variants.
Today, product fixed bundles can be published to custom storefronts once bundle publishing is enabled in the Partner Dashboard and the bundle product is published to the relevant sales channels.
However, variant fixed bundles, even when modeled correctly through the Admin API, cannot be published or exposed in the same way.
Why this matters
Variant fixed bundles are important for more granular and real-world merchandising use cases.
For example:
- Bundles tied to specific variants instead of whole products
- Size-specific or color-specific packs
- Build-specific configurations
- Tightly coupled variant combinations
- Different bundle configurations under the same product
- Cases where inventory, pricing, or availability needs to be driven at the variant level
Product fixed bundles work well in many cases, but they can become limiting when the bundle relationship needs to be precise at the variant level.
Current limitation
Because variant fixed bundles cannot be published to custom storefronts today, apps and merchants are often forced to use workarounds.
For example, we either have to:
- Remodel the bundle as a product fixed bundle, even when the catalog structure does not naturally fit that model, or
- Build custom abstraction layers in apps or storefronts, such as storing bundle relationships in our own database or metafields and manually handling component products on the storefront/cart side.
Both approaches add avoidable complexity.
They also increase the risk of data mismatches between Shopify Admin and the storefront, make maintenance harder, and create an inconsistent merchant experience across channels.
Requested enhancement
It would be very helpful if Shopify could add first-class publishing support for variant fixed bundles on custom storefronts.
Ideally, this would include:
1. Publishing support for variant fixed bundle parents
Variant-level bundle parents, or their associated products, should be publishable in a way that is consistent with product fixed bundle parents today.
2. Consistent Admin experience
Merchants should be able to publish and unpublish variant fixed bundles from the same Publishing section where they manage visibility across sales channels and apps.
It would also help if the Admin clearly indicated when a product or variant is acting as a bundle defined at the variant level.
3. Clear API and documentation support
The documentation could be updated to explain:
- How variant fixed bundles can be published
- How they should be consumed on custom storefronts
- How apps should model and manage them through the Admin API
- Any constraints compared to product fixed bundles
Examples similar to the existing product fixed bundle guidance would be extremely useful.
Benefits
Supporting publishing for variant fixed bundles would:
- Unlock more advanced bundling use cases that depend on variant-level relationships
- Reduce the need for custom app-specific workarounds
- Make it easier for merchants to manage bundles consistently across channels
- Keep bundle modeling inside Shopify’s bundle system instead of forcing every app or custom storefront to recreate this logic separately
- Improve reliability for custom storefront implementations
This would be especially valuable for merchants and apps building more advanced bundle experiences on top of Shopify’s native bundle infrastructure.
Thank you for considering this request.
If there are current technical constraints or roadmap considerations that make variant fixed bundle publishing difficult, it would be helpful to understand them so app developers can make better implementation decisions when choosing between product fixed bundles and variant fixed bundles.
