Understanding Syncs

A Sync is the connection that sends conversion data from your domains to a destination like Google Ads, Meta Ads, TikTok Ads, or Klaviyo. This article explains what a Sync is, what it does, and where to find your Syncs in Metrion.

What a Sync does
A Sync takes the conversions captured on your website and forwards them to an advertising destination on a recurring schedule (every two hours). Once configured, it runs automatically in the background — you don’t need to trigger it manually.

Each Sync defines three things: which domains the data comes from, where it’s sent, and which conversion goals are included. You can have multiple Syncs in the same installation, which is useful when you want to send different goals to different destinations or split brand websites across separate destinations.

The parts of a Sync

Domains. One or more websites that produce the conversion data. You pick from the domains attached to your installation.
Destination. The advertising platform that receives the data, such as a specific Google Ads or Meta Ads account.
Conversion goals. The events you want to send. Available goals depend on the destination — most support AddToCart, Purchase, BeginCheckout, PageView, and ItemView.
Enhanced conversions. A toggle that allows the Sync to send extra user data (hashed) to improve match rates on the destination platform.
Dynamic remarketing. Optional. Enable when the destination supports remarketing audiences and you want product-level data included.
Cancelled order updates. Optional. When enabled, refunds and cancellations are reflected back to the destination so reported conversions stay accurate.

Where to find your Syncs
Open Tracking → Syncs in the left sidebar. The page shows every Sync in the current installation, with one row per Sync.

Each row shows:

Status. The current health of the Sync (see the table below).
Domains. The websites included in this Sync.
Destination. The connected ad-platform account.
Last run. The most recent successful run, in your account timezone.

Click any Sync row to open its detail page, where you can edit settings, view the Flow diagram, or check Logs.

Sync statuses

Status	What it means
New	The Sync has been created but has never run yet.
Syncing now	The Sync is currently fetching data and forwarding it to the destination.
Synced	The most recent run finished successfully.
Streaming	Conversions are being forwarded continuously rather than in scheduled batches.
Failed	The most recent run did not complete. Open the Logs tab on the Sync to see what went wrong.

How often a Sync runs
Syncs run every two hours on a regular schedule. You can confirm the cadence by opening the Logs tab on a Sync and looking at the gap between successive “Import started” entries. If you need data sent for a specific historical window — for example after fixing a tracking issue — use a Backfill instead of waiting for the next scheduled run.
