Hi Bala,
If you are looking to pull over the use who edited the record the easiest way would be to bring over the Last Modified By field into a user field in your destination record. The issue with trying to use a ticket is that typically they wouldn't be dynamic. So a webhook wouldn't dynamically recognize and use the ticket for one user over another. Meanwhile the Last Modified by field will fill in with the user that initiated the change and then can be written into a user field in the created record. This way instead of only getting the Webhook owner as the record creator you can get the user who initiated the action as well.
