Storefront REST API
Commerce+ Storefront REST API documentation contains a list of resources that are provided by the Commerce+ REST API for retrieving, changing, and deleting data related to a store. Each REST resource contains information such as URLs, descriptions, and sample input and output data.
Most REST APIs require the storeId. To find your store ID, open the Store Management tool within the Commerce Lab and select your store. Then, view and note your store ID value that is displayed as the store's Unique ID.
