Conversions API

The Conversions API is a server-side connection that sends conversion events directly from your server to LINE instead of relying only on the browser-based LINE Tag.

You send events like purchase or sign-up from your server, so conversions still reach LINE when the browser tag is blocked, cookies are cleared, or a user drops off the site before the pixel fires. You typically run it alongside the tag, deduplicating shared events so the same conversion is not counted twice, which gives the optimization engine a fuller and more reliable signal.

A store implements the Conversions API through a server-side tag so completed checkouts post from its backend to LINE, capturing purchases that browser tracking missed and feeding cleaner data back to bidding.

Server-side is not automatically complete. If your event deduplication or parameter mapping is wrong, you either double-count conversions or send LINE garbage it optimizes toward. Validate the events landing on LINE's side against your own order data before you trust the reported numbers.

More durable signal, only if you wire it right.
