I'm look at using Zoho CRM. We have a custom built Project Management System.  I know it's not rocket science to use the Zoho API to add or update Accounts and Contacts from a 3rd party application.  But what about if a Zoho CRM User updates Account or Contact information within Zoho CRM.  Is there a method to sync the updates back to the 3rd Party system?  Can Zoho trigger a 3rd Party API to update a record any time an Account or Contact is updated (highly unlikely.)  Would the 3rd Party System essentially need to periodically (once a day) use the Zoho API to search for any Accounts or Contacts that were added or updated in Zoho?  How would you identify them, is there a create/update date/time stamp on all Account and Contact records in Zoho that can be returned by a record search API call?
