The APICBASE API is a RESTful API that provides list and detail endpoints for the following data entities:
For all of these data entities you can request all information that is stored in your library. With the API it is easy to export data automatically at regular intervals or develop custom integrations with existing software.
For user management we also provide POST, PATCH and DELETE endpoints in order to implement automated user management scenario's.
More technical details can be found here, although for these pages an account on apicbase.com is needed.
