<RequestExample>
  ```bash theme={null}
  curl https://api.thanxsandbox.com/users/:id \
    -X PATCH \
    -H "Content-Type: application/json" \
    -H "Accept-Version: v4.0" \
    -H "Accept: application/json" \
    -H "Authorization: Bearer ${token}" \
    -H "X-ClientId: ${client_id}" \

        "email": "<email>",
        "first_name": "<first_name>",
