Get a Message Id for the very last message in a conversation

[mario7lorenzo]

Hi, I would like to ask regarding to getting the messageId value of the very last message in a particular conversation. I want to do this since I want to do a syncing process daily and I think that it is more efficient to get all messages before the last message Id rather than get all messages after the very first message because our message will continuously grow and at a certain big number, we won't be able to fetch more data if we start from the beginning. Are there any suggestions? Thanks.

not the exact solution but in echo example they add the startime as a variable to the handler. What i do is remove and add handler with current time every time i connect and disconnect.

type waHandler struct{
    c   *whatsapp.Conn
    startTime uint64
}

wac.RemoveHandlers()
wac.AddHandler(&waHandler{wac, uint64(time.Now().Unix())})
session, err := wac.Disconnect()
if err == nil {
//restore session
          fmt.Println("Desconectado")
}
<-time.After(30 * time.Second)
session, err = wac.RestoreWithSession(session)
if err == nil {
    fmt.Println("Conectado")
}
<-time.After(30 * time.Second)
