Integrate Zoho login button with third party application

Integrate Zoho login button with third party application

Hello,

I'm having a problem with connecting an API to a third party application.
Currently I'm trying to generate the authorization code for a CRM API but I'm struggling to figure out how to put the "Login with Zoho" button on the website that the documentation says to click.

specific documentation: Authorization Request | Online Help - Zoho CRM

Anybody have any idea what to do. I don't know where to start on integrating the login button, I'm currently developing on Mendix.

Thanks,

Aaron
