Reg: Dialogflow unique id

[nareemani nirjogi]

Hello team, 

I am building a bot using Dialogflow ES and integrated it to the backend using NodeJS with fulfillment modules for providing Dynamic responses. To store the data in DB I need a unique id of every user. How to get that? 

Did Dialogflow give any unique id ?

Thanks

Hi!

I believe that the best way of getting an identification of every user would be to set up account linking in your bot [1]. Beware that users can also identify as anonymous using this method. 

Kind regards!

Thanks for the answer

It means, is Dialogflow didn't maintain any id for users for identification right? Please correct me If I am wrong

thank you.

Hey, 

As per the documentation at [1], your system will be responsible for generating unique session IDs while they can be random numbers, hashed end-user identifiers, or any other values that are convenient for you to generate, thus it does not look like Dialogflow would maintain the hashed end-user identifiers if applicable as session data is stored by Dialogflow for 20 minutes. 

However, it seems that you can use the userStorage object which is persisted across conversations when it can identify a user as per discussions at [2] that you can take a look.

Dialogflow already provide a Session ID. This session is available till the user hasn't continued the conversation about 20 minutes. But if the user is interacting with the bot without a gap of 20 minutes this session id (which is unique) can be used.

If you are referring to identify the user from your system then from the user interface code, pass the user ID in the webhook request, then you will get the same information in originalDetectIntentRequest field of the webhook request, refer to the docs below:

https://cloud.google.com/dialogflow/es/docs/fulfillment-webhook#webhook_request

We have implemented the user identification using this same approach in our product, refer to our docs to get an idea on how to pass and retrieve it https://docs.kommunicate.io/docs/bot-dialogflow-integration#pass-custom-data-to-bot-platform
