401 Unauthorized while trying to use https://desk.zoho.com/api

Hello,
I'm really struggling to get this api working with postman and so far nothing works . Let me elaborate what i'm trying to do using the api . I have went over the documentation and it got very confused , i tried getting all tickets using the info from : https://desk.zoho.com/DeskAPIDocument#Tickets#Tickets_Listalltickets , 
$ curl -X GET https://desk.zoho.com/api/v1/tickets?include=contacts,assignee,departments,team,isRead
  -H "orgId:2389290"
  -H "Authorization:Zoho-oauthtoken 1000.3d0a155402dbb59f776fd63adb1e67c0.a41ea557a6a8d7e402690098b2056f60s"

i have used the Zoho Api Console, created a Self Client with the Desk.tickets.READ scope, i got back the code that looks like the one from the example above ex.:"1000.3d0a155402dbb59f776fd63adb1e67c0.a41ea557a6a8d7e402690098b2056f60s" then in postman i used the orgId header with our orgid and the Authorization:Zoho-oauthtoken with the Zoho Api Console generated code and all i get back is {"errorCode":"INVALID_OAUTH","message":"The OAuth Token you provided is invalid."}. How do i make this work ? Thank you !
