New webhooks for pre-registration and talk submissions

You can now send outbound webhooks when an attendee pre-registers to be notified about your event, or when a speaker submits a talk proposal. Connect these moments to your email automations or CRM to nurture early interest and follow up with prospective speakers.

In Event Settings → API, MCP & Webhooks, click Add Webhook and choose Attendee pre-registered or Talk submission submitted, then enter the HTTPS URL that should receive the details. The existing Speaker added to event action is also available for speaker onboarding.

Pre-registration webhooks are sent once for an explicit pre-launch signup. Talk submissions trigger immediately for free submissions, or after successful payment for paid submissions; editing a proposal does not send it again.
