ZVA and Manage Engine integration

[LucaPaleari]

Hi everyone.

I'm trying to setup the integration between AVZ and Manage Engine ServiceDesk Plus.

Based on the KB https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0057946 I insert "itdesk" and select my region (EU).

I'm redirected to the auth page on Zoho but after the authentication process I land on an error page that says: 

Invalid Client

Client ID passed does not exist

Any idea?

Is the ServiceDeskPlus supported or do I miss something?

"itdesk" refers to other ManageEngine products?

Regards

Luca
