# Overview

> An overview of APIs to replace the entire user list.

For scenarios where you need to replace the entire user list rather than just updating a subset, follow these steps using the provided APIs:

* [Start Sync](/reference/start-sync): This API creates a draft version of the list where you can add or remove users.
* Update Users: [Add](/reference/add-subscribers-to-draft-list) or [remove](/reference/remove-subscribers-from-draft-list) subscribers to/from this draft version as needed.
* [Finish Sync](/reference/finish-sync): Call this API when you are done updating users in the draft version. The draft list will replace the current active list after calling this API.

If you create a draft version by mistake and decide not to keep it, you can [delete the draft list](/reference/delete-draft-list).
