I need to embed zoho tickets in some bash script using tickets api but the main problem is token generation.

Zendesk provide one token which we can use it everytime when we make request but here in zoho we have to go through two step gui process to generate auth token which is not feasible if i have to show tickets in my admin panel because oauth token have expiry time and refresh token can only be used 10 times, I guess ? 

So i basically want to know that if i can somehow generate token with the help of api in one step then i can use it to show details of tickets in my bash scripts

or there is any other way ?
