# /api/track stops working

Calls to /api/track on Klaviyo API stopped working on June 30, 2024.

On June 30, 2024, the /api/track endpoint was removed as part of the retirement of the legacy APIs. Calls sent to this endpoint now fail. Any integrations still directing traffic to /api/track must be updated to avoid broken event tracking.

## What to use instead

Send events using POST /api/events for server-side requests with a private key, or use POST /client/events with a public key.
