Synchronization does not require any manual operation.
During synchronization, all relevant metadata is stored or updated in the bookstore system, each time a book appears in the data stream (title, price, author name, abstract, cover image, etc.)
When a new book appears in the feed, it is created in your catalog.
When a book is marked as deleted in the feed, it is disabled in your catalog.
When a book goes "on sale" in the feed, it is created in your catalog.
When a book becomes "not available for sale", it is disabled in your catalog.
To download the cover image, the URL provided in the feed is used instead of built based on the platform's domain name.
