Hi guys, I hope you can help me with this one:

I’m developing an App using Unity3D (the game engine, which uses C# and JavaScript) and so far I’ve been able to access the Zoho CRM API correctly, getting refresh and access tokens, making GET and POST requests. I want my users to be able to log in with their credentials inside my App and make API calls to get/modify their own records (they might belong to an organization under my control), I’ve seen several threads on this topic and these ones seem to be the closest to what I want:

https://help.zoho.com/portal/en/community/topic/possible-to-use-rest-api-without-a-user-to-perform-the-interactive-login

Is there a way to authenticate users with username and password, send that information to the API and then receive refresh/access tokens to continue making API calls? Is there another way to identify the users with their respective Zoho CRM accounts? I’m using a Self Client, I don’t know how to get to work something web based, I’m not an expert in Zoho CRM either, so forgive me if I’m using incorrectly any term.
