FlareSync | Backfill

Step 1 Choose an Event

Paste an Event URL or Event ID. FlareSync will fetch all attendees, upsert them as contacts, and add them to a static list named exactly after the event.

Guide When to use this
  • You created or edited an event before the sync was live.
  • You are missing information on a HubSpot list for an upcoming event.
  • You want to restore lists after a manual cleanup or experiment.
Guide How it works
  1. FlareSync will fetch all attendees from Eventbrite for that event.
  2. For each email, FlareSync will find or create a HubSpot contact.
  3. FlareSync will set event_platform, last_event_*, gender, and birthday.
  4. FlareSync will create (or reuse) a static list named after the event and add the contacts.
