Posting data from my web application, to a custom module in Zoho CRM

Posting data from my web application, to a custom module in Zoho CRM

Good morning,

I am having trouble populating a custom module I've built from a form in my node.js application.

i do not want to use web forms because styling is going to be difficult. It is a multi-step form with lots of javascript. Much rather prefer to post form fields from my web app on every form submission to the custom module I've created.

What part of the docs do I need to look at for some examples considering we are now using Zoho V2. Lots of code seems to be outdated in the Node SDK Docs, its polluted with V1 examples.

i get 'authorization failure' as  a common error, which leads me to think I am not setting up my grant and auth tokens correctly.

Looking forward to your response,

Thanks
