Publish first
Embeds load the published version. Iterate in the builder, then republish when ready. Draft-only changes do not appear in the popup until you publish again - see Forms, publish, and versions (/docs/features/forms-publish-versions).
Pick popup mode
Use popup for interruptive CTAs, popover for lighter prompts, slider or side-tab for persistent entry points. All six embed modes are documented under Embed & share (/docs/features/embed-and-share), including when email embed and branding badges apply.
Pass attribution
Stamp UTM or user ids with hidden fields / URL parameters so Results stay attributable. The Embed & share doc (/docs/features/embed-and-share) covers hidden fields and URL parameters for campaign tracking.
Listen for events
Subscribe to submission and close events in the embed SDK to update your page UI after a finish. After go-live, verify completes in Results (/docs/features/results-and-csv) and confirm the published version matches what the popup loads.
