When you go to the upload page for a Webflow template it asks for HTML files but for a Webflow template you can’t really export it and if you do export the HTML it just becomes an HTML theme. When you buy a Webflow template on ThemeForest you get a code to redeem it on Webflow but how does one generate this code and upload their own template onto the Webflow section on ThemeForest?
I currently have this same problem. When I uploaded my Webflow template to Themeforest, redemption and purchase codes were not generated and customers cannot use the template on Webflow. I currently have a ticket submitted to the support team and am hoping for a fix.
