3rd party integration for ZOHO Desk

We want to integrate a helpcenter search bar and the possibility to directly add tickets to our cloud software.

We want to add a 'support bar' in our software where people have the search field to search for known articles.
When entering certain tags the right document should become available directly.

Just like the search requests in the ZOHO Desk environment direcly. Can you point us to the right API information?

We also want to be able to directly add a support ticket from our application.
Is this the correct article?
