[Koha] Need Help - SSO & API for Koha

Hi All, Can somebody help me to understand and give clarity for below two functionality in KOHA. 1. Single Sign On – Koha and Digital Library. (Can we use OAUTH2 for this or any other predefined functionality is available?). Idea is to have single user base for LMS and DL. If you have any architecture diagram, pls share with us. 2. Exposing API`s from KOHA for sharing analytics and some limited functionalities to other application. With regards, Mohan
