Introduction to Product Categorization API

Product categorization API is one of the most accurate e-commerce categorisation services on the market.

API can be used with raw texts as well as websites. You can send full-path URLs and obtain real-time, live URL based website categorization.

We use two different taxonomies for categorizations:

- Products Taxonomy (custom, related to Google Products Taxonomy), supporting three Tiers

- IAB Taxonomy, supporting two Tiers

Authentication

All requests should be made to endpoints that start with: https://www.productcategorization.com/api/

You need an API key to access our API endpoints and can obtain it by purchasing subscription to one of our plans.

Our API service expects for the API key to be included in all API requests to the server, as parameter:

api_key: b4dade2ce5fb2d0b189b5eb6f0cd

You must replace b4dade2ce5fb2d0b189b5eb6f0cd with your own API key, obtained upon purchasing one of our plans.

HTTP responses that are successful will have the status code 200 and the response formatted according to specification, please see documentation for examples.

Our servers return API data in JSON format by default.
