What is sent to a non-validating notary service when corda transaction is sent

Question

What info does the notary service see when Corda transaction is sent to the non-validating notary service for finalization?

Answer 1

The transaction is first filtered in the following way and then sent to non-validating notary service:
stx.buildFilteredTransaction(Predicate { 
    it is StateRef || it is TimeWindow || it == notaryParty 
})

The notary service will see:

Any inputs, in the form of StateRefs
The time-window, if it exists (since the notary is also the timestamping authority)
The identity of the transaction's notary
