I want to use gumroad to sell memberships by embedding their buy button widget into the forum e.g. via versatile banner theme component.
In order to remove any friction during checkout process, I want to prefill the user’s own email address into the embed code which is supported by gumroad, see here: Build Gumroad into your website - Gumroad Help Center
So the HTML code would look something like this:
<div class="gumroad-product-embed" data-gumroad-product-id="pencil" data-gumroad-params="firstname.lastname@example.org&price=10"> <a href="https://gumroad.com/l/pencil">Loading...</a></div>
Does discourse support something like that?
