Product variants

Product variant pages display information about individual product variations, including SKU, price, inventory levels, and option values like size or color. Extensions on these pages help merchants manage variant-specific workflows, sync inventory with external systems, and configure purchase options.

Anchor to Use casesUse cases

Inventory synchronization: Sync variant inventory levels with external warehouse management systems, 3PLs, or ERP platforms to maintain accurate stock counts across multiple locations and sales channels.
Pricing and cost management: Display cost information from suppliers, calculate margins, apply bulk pricing rules, or sync variant prices with external pricing engines and wholesale platforms.
Marketplace publishing: Push variant data to external marketplaces like Amazon, eBay, or Google Shopping, including SKU mappings, inventory levels, and marketplace-specific attributes.
Subscription and purchase options: Configure variant-specific subscription settings, bundle configurations, or pre-order options through external subscription management platforms.
Variant analytics: Display variant-level performance metrics, sales velocity, or demand forecasting data from external analytics platforms to help merchants optimize inventory.

Anchor to Product variant details targetsProduct variant details targets

Use action and block targets to extend the product variant details page with workflows and contextual information.

Extensions can query and mutate Shopify data using the direct API, or call your app's backend for custom business logic and external integrations.

Anchor to Product variant details action ,[object Object]Product variant details action target

admin.product-variant-details.action.render

Renders an admin action extension on the product variants details page. Merchants can access this extension from the More actions menu. Use this target to provide workflows that operate on product variants data, such as syncing with external systems, exporting product variants information, or managing credit terms.

Extensions at this target can access product variants data through the data property in the Action Extension API. The action renders in a modal overlay, providing space for multi-step workflows, forms, and confirmations.

Anchor to Product variant details action (should render) ,[object Object]Product variant details action (should render) target

admin.product-variant-details.action.should-render

Controls the render state of an admin action extension on the product variants details page. Use this target to conditionally show or hide your action extension based on the product variant's properties, such as status, configuration, or specific business requirements.

This target returns a boolean value that determines whether the corresponding action extension appears in the More actions menu. The extension evaluates each time the page loads.

Description

Add a should-render extension that checks your app backend to determine if a product variant has inventory synchronization enabled before displaying the action.

Add a should-render extension that displays the action only for product variants with stock available. This example uses the [direct API](/docs/api/admin-extensions/2026-04-rc#direct-api-access) to query the [GraphQL Admin API](/docs/api/admin-graphql) and check the variant's inventory quantity.

Anchor to Product variant details block ,[object Object]Product variant details block target

admin.product-variant-details.block.render

Renders an admin block extension inline on the product variants details page. Use this target to display contextual information, analytics, or status updates related to the product variants without requiring merchant interaction to open a modal.

Extensions at this target can access product variants data through the data property in the Block Extension API. Blocks appear as cards on the page and can show real-time data, insights, or quick actions, providing persistent visibility for information merchants need to see at a glance.

Anchor to Product variant details configuration ,[object Object]Product variant details configuration target

admin.product-variant-details.configuration.render

Renders a configuration interface for product bundles on product variant details pages. This target allows merchants to configure component products, quantities, and pricing for bundle configurations directly from the variant editor. Use this target when your app needs to provide merchant-facing configuration UI for bundle components and options.

Anchor to Best practicesBest practices

Display variant context clearly: Always show which product a variant belongs to (product title) alongside variant-specific details (option values, SKU). Merchants often view variants out of context and need this information to make decisions.
Aggregate inventory across locations: When displaying variant inventory, show total inventory by default but allow filtering by location. Merchants with multi-location setups need location-specific visibility for fulfillment decisions.
Validate marketplace requirements: Before publishing variants to external marketplaces, validate that required variant fields (SKU, barcode, weight, dimensions) are populated. Many marketplaces reject variants missing these fields, and early validation prevents failed sync attempts.
Handle option combinations carefully: Variants are defined by option combinations (for example, Size: Large, Color: Red). When building extensions that manipulate variants, preserve the option structure and validate that option combinations remain unique within the product.
Check inventory tracking status: Use inventoryItem.tracked to determine if a variant tracks inventory before displaying inventory-related actions. Extensions that assume all variants track inventory will fail for digital products or services.

Anchor to LimitationsLimitations

Single target per module: Each [[extensions.targeting]] entry in your TOML configuration maps one target to one module file.
Purchase option target visibility: The admin.product-variant-purchase-option.action.render target only appears when the product variant has a selling plan group associated with it.
Configuration target availability: The admin.product-variant-details.configuration.render target only appears for product variants configured as bundles.
Block target visibility: Block extensions must be manually added and pinned by merchants before they appear.
Block collapse behavior: Returning null from a block extension collapses the block rather than removing it from the page. Blocks can't be fully hidden at runtime.
