How can I retrieve sender id passed to my web hook to fill the slot value

Hello All, I am trying to get the sender_id which is being passed to my webhook with the sender message. When a person initiate a conversation, I am trying to get the sender id ,which would be different for each user and setting the slot with the same value so that I can use it to retrieve the name of the sender from my database and do some personalization. Is there any way to do so? Any help would be greatly appreciated.

@yash_tanu It all depends on what information you are collecting from the user, according to GDPR policy. You can store the bot/user conversation whilst using Tracker store for any database Tracker Stores after that you need to write custom action to retrieve the sender id and user name etc for the slot filling. Can you give some example for more information. I hope my point is clear to you?
