Changing a Group Owner

A group owner can delegate the ownership to another user as shown below:

curl -v -X PUT \
  -H "Authorization: Bearer {ACCESS_TOKEN}" \
  -H "Content-Type: application/vnd.kii.GroupOwnerChangeRequest+json" \
  "https://api.kii.com/api/apps/{APP_ID}/groups/{GROUP_ID}/owner" \
  -d '{"owner": "{USER_ID}"}'

Once the ownership is delegated, the former group owner becomes a group member.
