We love using Zoho Learn to manage our internal trainings and knowledge base. What we'd really love is to be able to query Learn via API so that in Zoho Projects, Zoho Creator, or Zoho Desk, we can recommend relevant Learn articles and manuals to team members. As we all know, a knowledge base is no good if people don't look for answers in there! 

I know that with WorkDrive, for example, there were APIs available before any official documentation was published. Are there any REST API endpoints available for Zoho Learn?
