Submit Signup Form

You can submit an embedded signup form or popup without an API key. The endpoint accepts application/x-www-form-urlencoded form posts and JSON.
Forms created in the dashboard post to the saved form endpoint, which stores audience targeting and success behavior server-side. This company-level endpoint keeps working for popups and existing deployed embeds.
