Hi Jep,
Thanks a million for your quick response.. Here are a couple of things:
1. We need to use a field that can be exposed via SOAP API.. We don't see that Updated or Updated AT being exposed in API.. To be honest, if updated field was exposed via API, we would not need what we are tring to do.. Do we have it right?
2. As a result of API limitation, we were trying to use the custom field.. Given our purpose, I'm not sure (as I'm new to Marketo) how to implement what you have recommended for custom field.. Where do we set this up?
Many thanks in advance.
