nit: I would put this into a separate function because this is the same code 6 times. We could also change the signature of transaction_event_req to not take a std::optional but just a bool instead and always report true or false in every TransactionEvent.req message

I also considered changing the signature, but from what i understand from the specs , only flags with "true" are generally reported and this flag is false by default so i left it optional.

As far as I understand to are also allowed to set it to false in case you are online..

My 2 cents on this: Only send the offline value if we were offline and otherwise omit it. All the functionality is there and it saves a bit of data, even if its a minor amount.
You could indeed change it to a bool in transaction_event_req and do the omitting in that function.
