# Undo a merge

`POST /v1/people/{id}/split`

## Request

- Base URL: `https://api.mentio.dev`
- URL: `https://api.mentio.dev/v1/people/{id}/split`
- Auth: HTTP bearer

The account becomes its own person again. With `groupId`, the call works inside that keyword group: its people, and its own tags, notes, mute, merges and activities, apart from the workspace's and from every other group's.

## Path parameters

- `id` string, required: Person id (aut_...).

## Query parameters

- `groupId` string: Scope to one keyword group (grp_...): only people who mentioned that group's keywords, with that group's own tags, notes, mute, merges, activities and segments. Omit for the whole workspace.
