Difference between notebook id by OfficeJS and OneNote API

Question

I\'m trying to build task-pane add-in for OneNote ClassNotebook.

I want to know whether current user is teacher or student.

To achieve this, my plan was:

Answer 1

EDIT: I'm happy to say this is now available, use GetRestApiID for this.

At this moment, the OneNote REST API and OneNote add-ins have imcompatible id's. There is a uservoice entry for this: https://onenote.uservoice.com/forums/245490-onenote-developer-apis/suggestions/17010982-add-onenote-add-ins-to-onenote-api-compatible-ids

For now, you'll have to rely in something like the URLs or the names.
