Access Zoho Books Api with CRM SDK access Token

Access Zoho Books Api with CRM SDK access Token

Hello ,
Im currently trying to connect to our System to Zoho Books.
and i figured that the access token from CRM is the same.
I also edited the scope.

but while trying with Postman I only got : 

  1. {
  2.     "code": 57,
  3.     "message": "You are not authorized to perform this operation"
  4. }
Can I use the CRM SDK access token ?
