# Checksums added to assets

As of the 2020-10 REST API, checksums will be provided on assets that were recently updated.

If you use a client that supports checksums (ie Theme Kit 1.1 or newer), then the time it will take to sync your local files and the bandwidth used will be drastically reduced.

For more information, please see the checksum field in the [REST API](https://shopify.dev/docs/admin-api/rest/reference/online-store/asset?api%5Bversion%5D=2020-10).
