The Webservice validate three data to provide access to the information:


  1. User
  2. Token
  3. IP address


In this case, if the invocated method shows a code 4, this indicates that the IP address from where sent the request is not correct so that it is necessary to verify the information. If you have not or do not remember this information you can request it by email to md.support@grupombv.com.mx
