Not available yet. The embed script and the rule that lets public form pages be framed are on qa (row F-M01) but switched off by default (build flag FORMS_EMBED_HEADERS), and the public form page they point at (/f/) is on qa, so a form's short link opens. Framing stays blocked until the build flag is on, and no screen gives you the embed code yet. Nothing below can be used today.
Can I show my form inside my own website?
One script tag carrying your form's id, with modes for inline, popup, slider, side tab and full page, and automatic height.
Can other sites frame any page of Finocket?
No. Only public form pages will allow framing. The app itself stays blocked from being framed.
Does an embedded form set cookies?
The plan is none: the draft token is kept in memory and in the link.
