Call Zoho API via API

Call Zoho API via API

Hi,

Is it possible create ticket via api without oauthToken? I tried call Zoho API from my back-end with authorizationToken generated in https://accounts.zoho.com/apiauthtoken/create?SCOPE=ZohoSupport/supportapi,ZohoSearch/SearchAPI.

and allways I get "errorCode":"UNAUTHORIZED","message":"You are not authenticated to perfom this operation."

Regards
