I'm looking to integrate membership functionality into my Webflow site to enable paying users to subscribe to my framable market research tools with Stripe. These iframable tools have personalized elements (ex. watchlists & preferences) so I need to a user-specific token to general the dynamic URL. Since Webflow does not allow server-side languages within their sites, this does not appear possible with their native memberships functionality. Is this something possible with Memberstack?
