ZohoSDK Api v2 C# - Connect to CRM

Hello Zoho,

I'm currently testing out the ZohoSDK API v2.
I've managed to connect to the CRM and have been able to get some details from the CRM or insert a Lead into the CRM. So far so good.

However, to get this to work, I need to use the https://accounts.zoho.eu/developerconsole to generate a grant Token and paste this is my code. This gives me back an accessToken and a refreshToken. I don't want my endusers to have to do this .. ever, because it's troublesome and cumbersome.

I have 2 questions:
1) Is there a way to make my program request the accessToken en refreshToken without having to use the https://accounts.zoho.eu/developerconsole site?

2) Is it possible to get this done without using the SDK?

Thanks in advance!
