# Change a member's role

`POST /v1/workspaces/{workspaceId}/members/{userId}/role`

Owners and admins can change roles. Only the owner can demote an admin. Making someone a guest removes them from every teamspace; they keep pages shared with them directly.

Scope: `docs:write`.

curl -X POST "https://api.lydie.co/v1/workspaces/01JCQ3TZ0WJ8K4M2X7T9R6N1PA/members/kG7qL2m9XzP4tR8w/role" \
  -H "Authorization: Bearer $LYDIE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "role": "admin"
  }'
```
