You can promote an event on an external landing page while still using HeySummit for checkout, registration, attendee access, and event content.
Choose the right path
Send visitors to normal HeySummit checkout: link your external page to the event's registration flow.
Send visitors to one ticket or offer: use a direct checkout link.
Take payment in ThriveCart: use the ThriveCart Checkout integration so successful purchases create or update the attendee and grant the mapped ticket.
Register people collected elsewhere: follow the consent and ticket-assignment steps in Import attendees into your event.
Prefill an email address
If your external form redirects directly to a HeySummit checkout URL, it can add a valid email address as the email query parameter. URL-encode the value before redirecting.
Example: https://your-event.heysummit.com/checkout/register/?email=alex%40example.com
If the checkout URL already contains a query string, add &email=... instead of starting another query string. Current checkout prefill supports the email address; do not rely on a name parameter. Prefilling does not complete registration or purchase a ticket. The visitor must still complete the required HeySummit checkout steps, consent choices, and any custom registration fields.
Privacy and testing
Do not put a real person's email address into a public or reusable link. Build the redirect for the person who submitted your external form.
Test the complete path with a test address before sharing it, including ticket access, required fields, payment, and the final attendee confirmation.
Keep pricing, availability, consent wording, and attendee access rules consistent between the external page and HeySummit.
