ServiceNow and SDP : Two Way Communication for UPDATES?

ServiceNow and SDP : Two Way Communication for UPDATES?

HI All -

I've been reading documentation on ServiceNow and SDP API integration and I have a question. It seems when configured, the API can automatically create a ticket in SDP from ServiceNow and visa-versa (create a ticket in ServiceNow FROM SDP). 

However, does it also log the updates to the ticket? For instance, field changes, conversations, etc? Or is it just OPEN and CLOSE? Meaning, if a conversation is appended to the ticket in ServiceNow, will it automatically push it to SDP? And Visa versa?

Thank you
