Chargify.js on Unbounce page

I’m trying to embed a Chargify signup form on our Unbounce landing pages. The main method seems to be using Chargify.js. Has anybody done this before with any success?

I read the documentation and it’s completely foreign to me so I’ll obviously have a developer handle the implementation. I’m mostly curious if this is even doable with Unbounce, or if I’m wasting my time.

Thanks!
