Add a fixed bundle

A fixed bundle is the default implementation to support basic bundle use cases across Shopify’s ecosystem. These include standard bundles and multipack bundles that fit within Shopify’s variant limits.

This guide shows you how to add a fixed bundle using the GraphQL Admin API.

Your app can make authenticated requests to the GraphQL Admin API.
Your app has the write_products access scope. Learn how to configure your access scopes using Shopify CLI.

How it works

A bundle is modelled as a variant (the parent bundle) and is associated with other variants (bundle components) using the ProductVariantComponents relationship.

The bundle variant price determines the bundle price, while the component's variants inventory determines the bundle inventory.

A variant has a productVariantComponents field that determines the bundles' components. Two bundle variants can have the same components.

A diagram showing the relationship between product variants that model a bundle

The following diagram shows an example of a product variant ("The Hair and Skin Bundle") that models a bundle and contains two components: "Natural Shampoo 50 ml" and "Coconut Conditioner". The bundle is modelled by creating a variant, associating the variant with components, and assigning a quantity of one to each component.

Limitations and considerations

A bundle can have up to 30 components.
After an app has assigned components to a bundle, only that app can manage the components of the bundle.
Nested bundles aren't supported. A bundle can't have components and be part of another bundle simultaneously.

Step 1: Create a product with variants

Anchor link to section titled "Step 1: Create a product with variants"

To create a product with variants, you can run the productCreate mutation.

The following example creates a product with a single variant modelling a bundle.

Step 2: Associate components to variants

Anchor link to section titled "Step 2: Associate components to variants"

After creating the product variant, you need to associate the components of a bundle. To do that, you can run the productVariantRelationshipBulkUpdate mutation.

If the variant is associated with components, then the attribute productVariant.requiresComponents returns true.

The following example associates two components with a quantity of one to the product variant created in the previous step.
