Custom frontend & Zoho Creator backend

Custom frontend & Zoho Creator backend

For a client, we want to build a Zoho application with a custom frontend. The custom frontend has to be pixel-perfect, so we are going to have it built in Angular by a frontend developer.

Are there any users among you who have experiences with this? What are your tips & tricks? Are there limitations for fetching data directly through the Zoho API? ...?

I would love to hear your thoughts on this.
