GET/category_tree/{category_tree_id}/get_category_subtree
This call retrieves the details of all nodes of the category tree hierarchy (the subtree) below a specified category of a category tree. You identify the tree using the category_tree_id parameter, which was returned by the getDefaultCategoryTreeId call in the categoryTreeId field.
Note: This call can return a very large payload, so you are strongly advised to submit the request with the following HTTP header: Accept-Encoding: application/gzip
With this header (in addition to the required headers described under HTTP Request Headers), the call returns the response with gzip compression.
Input

This method is supported in Sandbox environment. To access the endpoint, just replace the api.ebay.com root URI with api.sandbox.ebay.com
URI parameters
| Parameter | Type | Description |
|---|---|---|
| category_tree_id | string | The unique identifier of the eBay category tree from which a category subtree is being requested. Occurrence: Required |
| category_id | string | The unique identifier of the category at the top of the subtree being requested. Note: If the category_id submitted identifies the root node of the tree, this call returns an error. To retrieve the complete tree, use this value with the getCategoryTree call. If the category_id submitted identifies a leaf node of the tree, the call response will contain information about only that leaf node, which is a valid subtree. Occurrence: Required |
HTTP request headers
All requests made to eBay REST operations require you to provide the Authorization HTTP header for authentication authorization.
The table below shows additional HTTP request headers that are either required, conditionally required, or strongly recommended for this method. Other standard HTTP request headers- opens rest request components page (not in this table) can also be used, but they are optional.
| Header | Type | Description |
|---|---|---|
| Accept-Encoding | string | This header indicates the compression-encoding algorithms the client accepts for the response. This value should be set to application/gzip. For more information, refer to HTTP request headers. Occurrence: Strongly Recommended |
OAuth scope
This request requires an access token created with the client credentials grant flow, using one or more scopes from the following list (please check your Application Keys page for a list of OAuth scopes available to your application):

Sample 1: Get a subtree of a category tree
This sample retrieves the complete content of a subtree of an eBay category tree, using the category tree node that contains the specified category as the root of the desired subtree.
Input
Use the category_tree_id path parameter to specify the category tree, and use the category_id query parameter to specify the category in the category node at the top of the subtree being requested.
GEThttps://api.ebay.com/commerce/taxonomy/v1/category_tree/0/get_category_subtree?category_id=11450
Output
A successful call returns the complete category subtree specified, from the specified category node to all leaf nodes of the subtree. In this sample, the returned category subtree contains almost 600 categories, so the response shown here has most of the nodes removed for easier viewing.
