Let's say John is visiting the Zylker website to request a ZPad replacement, as his screen is broken. Because he has already purchased a Zylker product, the Webhook block will try to retrieve his name or email address from the database using API calls. If he is already a contact in their business account, the bot will create a ticket for John and submit his ticket ID as confirmation. If John is not a contact, then it will go ahead and create a contact and then create a ticket ID for John. The webhook block here helps in finding out if John is an existing customer or not, and if yes, it will fetch all his details and ease the process of ticket creation.
