  title: Addresses Introduction Account Addresses Hierarchies API
  description: 'The Addresses API allows you to organize account addresses. Addresses are a sub-resource of `account` resources, an account can have multiple addresses, such as home, work, and neighbour.


    You can use an account address with either [client_credentials access token](/docs/api/authentication/create-an-access-token) or a combination of [implicit access token](/docs/api/authentication/create-an-access-token) and [Account Management authentication](/docs/api/accounts/post-v-2-account-members-tokens) token.

For example, a node with a `sort_order` value of `3` appears before a node with a `sort_order` value of `2`.\n\n - If you don’t provide `sort_order` when creating nodes, all child nodes in the response for Get a Node’s Children request are ordered by the `updated_at` time in descending order, with the most recently updated child node first.\n - If you set `sort_order` for only a few child nodes, the child nodes with a `sort_order` value appear first and then other child nodes appear in the order of `updated_at` time.\n\n You can also specify a `sort_order` when creating a node relationship.\n\n - If you create a node (**Node A**) with a `sort_order` and then you create a relationship for **Node A** with another node (**Node B**), the `sort_order` you specified when creating **Node A** is overwritten.\n - If you create **Node A** and then you create a relationship with **Node B** but do not configure a `sort_order`, the `sort_order` you specified when you created **Node A** is not overwritten.\n  \n ### Curating Products in a Node\n  \n  You can curate the products in a node. Product curation allows you to promote specific products within each node of your hierarchies, enabling you to create unique product collections in your storefront. For example, you may find you have an abundance of cotton T-Shirts and you want to promote these products to the top of the product list. When a shopper navigates to T-shirts, the cotton T-Shirts are displayed first.\n  \n  You can do this by adding a `curated_products` attribute to the body of your request and adding an array of product IDs to the attribute. You should add the products IDs in the order you want them to be displayed in your node. The first product ID is displayed first in the product list.\n  \n  You can only curate 20 products or less. You cannot have more than 20 curated products.\n  \n  - The product IDs you provide must exist in the specified node.\n  - If a curated product is removed from a node, the product is also removed from the curated_products list.\n  - Once you have curated the products in a node, you can use the get node products endpoint to retrieve a list of curated products.\n  \n  You can then display your curated products in your catalogs using the following catalog endpoints.\n  \n  - Get a node in your latest catalog release.\n  - Get a node in a catalog.\n  - Get all nodes in your latest catalog release.\n  - Get all nodes in a catalog.\n  - Get node children in your latest catalog release.\n  - Get node children in a catalog.\n"

You can do a partial update, where you specify only the field value to change.\n\n<CASummary />  \n```\n\n### Sorting Nodes in a Hierarchy\n\nYou can sort the order of your nodes, regardless of where the nodes are in the hierarchy.\n  \n The node with the highest value of sort_order is displayed first. For example, a node with a `sort_order` value of `3` appears before a node with a `sort_order` value of `2`.\n  \n - If you don’t provide `sort_order` when creating nodes, all child nodes in the response for Get a Node’s Children request are ordered by the `updated_at` time in descending order, with the most recently updated child node first.\n - If you set `sort_order` for only a few child nodes or not all, the child nodes with a `sort_order` value appear first and then other child nodes appear in the order of `updated_at` time.\n  \n You can also specify a sort_order when creating a node relationship.\n\n - If you update a node (**Node A**) with a `sort_order` and then you create a relationship for **Node A** with another node (**Node B**), the `sort_order` you specified when updating **Node A** is overwritten.\n - If you have updated **Node A** and then you create a relationship with **Node B** but do not configure a `sort_order`, the `sort_order` you specified when you updated **Node A** is not overwritten.\n  \n ### Curating Products in a Node\n\n You can curate the products in a node. Product curation allows you to promote specific products within each node of your hierarchies, enabling you to create unique product collections in your storefront. For example, you may find you have an abundance of cotton T-Shirts and you want to promote these products to the top of the product list. When a shopper navigates to T-shirts, the cotton T-Shirts are displayed first.\n\n You can do this by adding a `curated_products` attribute to the body of your request and adding an array of product IDs to the attribute. You should add the products IDs in the order you want them to be displayed in your node. The first product ID is displayed first in the product list.\n\n You can only curate 20 products or less. You cannot have more than 20 curated products.\n  \n - The product IDs you provide must exist in the specified node.\n - If a curated product is removed from a node, the product is also removed from the curated_products list.\n - Once you have curated the products in a node, you can use the get node products endpoint to retrieve a list of curated products.\n  \n You can then display your curated products in your catalogs using the following catalog endpoints.\n  \n - [Get a node in your latest catalog release](/docs/api/pxm/catalog/get-node)\n - [Get a node in a catalog](/docs/api/pxm/catalog/get-by-context-node)\n - [Get all nodes in your latest catalog release](/docs/api/pxm/catalog/get-all-nodes)\n - [Get all nodes in a catalog](/docs/api/pxm/catalog/get-by-context-all-nodes)\n - [Get node children in your latest catalog release](/docs/api/pxm/catalog/get-child-nodes)\n - [Get node children in a catalog](/docs/api/pxm/catalog/get-by-context-child-nodes)\n"

        #### Filtering

      summary: Create relationships between a hierarchy and child nodes
      description: 'Use this endpoint to create relationships between a hierarchy and one or more child nodes. You can create a relationship only if:


        - All child nodes already exist.

        - Every child node in the request body must belong to this hierarchy.

        - All siblings in a hierarchy must have a unique `name` and `slug`. Siblings are the child nodes that are related to the same parent.


        ### Sort Order


        You can also provide `sort_order` information when you create a relationship by adding a `meta` object to the array of node reference objects for each child node that requires sorting.


        The node with the highest value of `sort_order` appears at the top of the response. For example, a node with a `sort_order` value of `3` appears before a node with a `sort_order` value of `2`.


        - If you don’t provide `sort_order` when creating relationships, all child nodes in the response for Get a Hierarchy’s Children request are ordered by the `updated_at` time in descending order. The most recently updated child node appears at the top of the response.

        - If you set `sort_order` for only a few child nodes or not all, the child nodes with `sort_order` value appear first in the response and then other child nodes appear in the order of `updated_at` time.


        You can also specify a `sort_order` when creating and updating a node.
