On your Storefront products are organized or grouped in logical groups called Collections. The main purpose of collection is distribution management by displaying products on your website based on separate browsing structures required to achieve specific merchandising objectives, such as organizational requirements, multi-regional assortments, multi-channel assortments, and collections.
This endpoint gets collection details of a published product by ID. You can refine your search results by specifying query parameters - collectionIds and collectionRootName
Note:
1. You can narrow down the results by specifying offset and limit. When they are not specified, by default, you'll get up to 10 products.
2. If you don't have item ID, use the corresponding product ID-based or SKU-based endpoints.
