Note: The General Availability (GA) version of the Taxonomy API has been released. Developers currently using the Beta version should make plans to migrate to the new GA version, as the Beta version will be decommissioned on March 31, 2021. Until that date, the Beta version documentation set can be accessed through the All API Documentation page. A given eBay marketplace might use multiple category trees, but one of those trees is considered to be the default for that marketplace. This call retrieves a reference to the default category tree associated with the specified eBay marketplace ID. The response includes only the tree's unique identifier and version, which you can use to retrieve more details about the tree, its structure, and its individual category nodes.
