The Item Search API is a configuration driven API, which is determined by your Search Settings. For example, items returned in the API response data can be filtered by the facets you defined on the Search Index subtab when you set up Search Settings. For more information, see Search Settings Overview.
The Item Search API uses a REST/JSON style of communication, and supports searching, sorting, faceting, pagination, or any combination of these as they can operate independently. Web Developers can use this API to build facet filtering and keyword search on item data.
To use the Item Search API, you must have a Commerce web store or SCIS, and you must have configured item search settings for your site.
