Hello, I am trying to start using zoho as our CRM, and the first thing I need to do is importing the leads. 

I must do that through the API, and I have spent the past 3 hours going circles with Oauth, creating apps, clients and whatnot. 

So I decided to finally ask, what the heck am I missing, or is it really that complicated to get an API key to add the leads?

P.s I am looking to use simple CURL requests only.

Thank you, Tomas.
