Help with Webflow landing page integration with streamlit app hosted on Railways!

Hello Everyone,

I'm a Saas newbie and have managed to make myself a rough product on python using streamlit.

I would love to take advantage of the webflow integration with memberstack and stripe and then redirect my customers to either the free or paid programs hosted on my railways server.

I'd like both of them to share a common domain or a '/' version if possible but I cannot for the life of me figure out how to do this. Im not sure if I'm missing something very obvious but I'd really appreciate some help. Any Recommendations on hosting that integrate better with webflow would also be very appreciated.

Thank You!
