Adding items to CMS via API

Hi there!
I was wondering if it is possible to add CMS items into a collection list via the API? I have looked through the documentation and it only mensions GET request, but what if I have a program from where I want to be able to add elements to my webflow site cms?
I am working on my own user management system application that is running on my webflow site via the embed code. I would like for users to be able to add items to my CMS, for instance on gallery. Is this possible?

Also simple side question: I can’t find any documentation on how to make line spacing. I know how to make letter spacing, but how do I space lines within the same text block?

Make sure you know the CMS limits first before building your app.

Typography > line height
