Overview

Greet pulls registration data from Certain automatically on a scheduled basis. But sometimes you need data right now: a last-minute registrant, a session update, or a discrepancy you want to resolve before the doors open. The Data Sync page lets you trigger an immediate sync, adjust sync frequency, freeze inbound data, and push check-in status back to Certain.

Navigating to Data Sync

From the Account Dashboard, click the event you want to sync. On the event's Overview page, click Data Sync in the left sidebar.

At the top of the page you'll see the connected account name and an All entities synced timestamp showing when Greet last successfully pulled data for this event.

Sync Frequency

The Sync Frequency card shows how often Greet automatically pulls data for this event.

The default setting, Use account default, follows Greet's adaptive sync schedule: every 5 to 15 minutes before the event start date, then every minute once the event day arrives. If you need a different cadence for a specific event, use the dropdown to override the account default.

Triggering a Manual Sync

The page has three sync cards: Attendees, Sessions, and Session Registrations. Each card shows the last sync time, the total record count, an enable toggle, and a Sync Now button.

Click Sync Now on the relevant card to pull the latest data from Certain immediately. The card briefly shows that a sync is in progress, then the Last sync timestamp updates when the pull is complete.

Each card also has an enable toggle. If your event doesn't use sessions or session registrations, turn those off to skip unnecessary API calls and keep sync focused on attendee data.

Sync Settings

Scroll down past the sync cards to find two additional controls.

Freeze Inbound Sync temporarily stops Greet from pulling new data from Certain. Turn this on if you've locked down the attendee list and don't want any last-minute records coming in before the event.

Realtime Sync (Check-in Updates) runs in the opposite direction: it pushes check-in status changes from Greet back to Certain as soon as attendees arrive. This is on by default and is what keeps your Certain registration data current with what's happening at the kiosk.

Admin Actions

The Admin Actions section has a single button: Resync Check-ins. Clicking it pushes every checked-in status from Greet back to the connected Certain account. Use this if Realtime Sync was turned off during the event, or if you need to reconcile data after the event closes.

Connection Details

Expanding the Connection Details section shows the integration metadata Greet is using for this event: the Account Code (the parent Certain account) and the Event Code (the unique Certain event identifier).

The Event Code is what to share with Certain Support when filing a ticket about sync issues. It's how Certain's team locates the same event on their end. The section also lists the API endpoints Greet calls to pull data from Certain, which your technical team can copy and test directly.

A Few Things to Know

Triggered a sync but a record didn't appear? Greet only syncs records that carry the correct tag in Certain and have a completed registration status. Check both conditions in Certain before triggering another sync.

Realtime Sync was off mid-event? Use Resync Check-ins in Admin Actions to push all checked-in statuses back to Certain at once.
