In Bot Framework, what Unique ID should I use to save session?

Question

I am using bot framework and I am saving the session.messageAddress so I can send the user a msg later. I want to track each unique user I get. In case if they send me another msg again I will know I have already received a msg from them earlier. What unique ID should I use to identify the user?

I was thinking of using session.message.address.conversation.id, is this correct?

Refer to https://learn.microsoft.com/en-us/azure/bot-service/bot-service-resources-identifiers-guide?view=azure-bot-service-3.0

Every bot and user has an account within each channel. The account contains an identifier (id) and other informative bot non-structural data, like an optional name. Example: "from": { "id": "[email protected]", "name": "John Doe" }

You should use session.message.user.id to identify the user. Using the conversation id won’t work because the user can start a new conversation with the bot by simply reloading the web chat page and a new conversation id will be generated.

Edit

I mistakenly wrote session.from.id to identify the user. The correct way to do it is session.message.user.id!

Say that the user John Doe is chatting to the bot through Skype then message.user.id = "[email protected]" and message.user.name = "John Doe". And there you have it! your unique user id!

The session object will look like this:

"session": 
{
    /*...*/
    "message": 
    {
        /*...*/
        "user":
        {
            "id": "[email protected]",
            "name": "John Doe"
        }
    }
}
