Get a Node's Children

GET 
/pcm/catalogs/:catalog_id/releases/:release_id/nodes/:node_id/relationships/children

Returns the child nodes for a node from a published catalog.

note

Currently, published catalogs are limited to the current release and two releases prior to the current release.

You can see the parent nodes a node is associated with in the bread_crumb metadata for each node. This is useful if you want to improve how your shoppers search your store, for example. See Product and Node Associations in Breadcrumb Metadata.

In a catalog, you can use a filter to return a list of nodes in a hierarchy structure that a product belongs to. You can use this to build breadcrumbs in your storefront. For more information, see Building breadcrumbs in a storefront.

The response lists the products associated with the nodes. If products are curated, they are displayed in curated_products. Product curation allows you to promote specific products within each of your hierarchies, enabling you to create unique product collections in your storefront.

• If you don't provide any curated_products, products are listed by their updated_at time in descending order, with the most recently updated product first.
• If you configure curated_products for only a few products, the curated products are displayed first and the other products are displayed in the order of updated_at time.
• You can only curate 20 products or less. You cannot have more than 20 curated products.
• If a curated product is removed from a node, the product is also removed from the curated_products list.
• A product that is curated has the "curated_product": true attribute displayed.

Filtering

This endpoint supports filtering. For general syntax, see (/docs/commerce-cloud/api-overview/filtering). The following operators and attributes are available.

Operator	Description	Attributes	Example
Eq	Checks if the values of two operands are equal. If they are, the condition is true.	name, slug	filter=eq(name,some-name)
in	Checks if the values are included in the specified string. If they are, the condition is true.
Id	filter=in(id,9214719b-17fe-4ea7-896c-d61e60fc0d05,e104d541-2c52-47fa-8a9a-c4382480d97c,65daaf68-ff2e-4632-8944-370de835967d)

Building breadcrumbs in a storefront

In a catalog, you can use a filter to return a list of nodes in a hierarchy structure that a product belongs to. You can use this to build breadcrumbs in your storefront. An example is shown below.

filter=in(id,c83bfe55-0d87-4302-a86d-ab19e7e323f1,6003d7ef-84f3-49bb-a8bd-4cbfa203dcbb)

• Specify the node Ids in the filter expression.
• You can have as many node Ids as you want.
• It does not matter what order you specify the node Ids. The nodes are returned in the order they were last updated.
