taxons

The taxons query allows you to return the categorization hierarchy, or Taxonomy as it’s referred to in Marketplacer.

Key Information

Use-Case

The categorization hierarchy defines both where products sit, and what attributes those products have, (via Prototypes). There are a number of use cases for using the taxonomy query, but perhaps the most common one would be so that Sellers can create products correctly in Marketplacer when using the API (products will be considered invalid if they have not been created with a valid category / taxon).

Further Points of Note

Taxons are hierarchical, in that they can recursively have children.
To ensure you query all descendants for a given taxon, you need to ensure you query the children at each layer, an example querying a 5 level taxonomy is shown below
From a usability perspective, categorization hierarchies (taxonomies) with a depth greater than 5 are sum-optimal and should be avoided
