Zoho api error Invalid Client, Client ID passed does not exist

I am trying fetch customer data using postman from zoho books api.

I created an account in https://www.zoho.com/in/books/ then I created a new customer there.

After that I created a client-based application here https://api-console.zoho.com/ and got the client_id and client_secret

Now to get the code according to https://www.zoho.com/books/api/v3/oauth/#overview I put client_id and redirect_uri in the below url and browsed it. I was supposed get the code but getting this error.
