It is possible to update the ebook catalogue by using the metadata obtained with the following API:

  1. The API for a full synchronization of the catalogue, which retrieves the complete metadata of all the publications.

  2. The API for a differential synchronization of the catalogue, which retrieves the complete metadata of the publications modified since the last synchronization or a precise date.

  3. The API for a synchronization of one publication, which retrieve the complete metadata of the requested publication.


The retrieved metadata are divided in several files (ONIX or XML), each one of them containing the metadata of up to 50 publications.
