Freshdesk Delete contact with trigger webhook

Hi community,

I am trying to delete a contact by using a wehbook automation in Freshdesk. 

When I know the ID of the contact, the webhook is working, example: /api/v2/contacts/123456, but I don’t know how to generalize for any contact ID. There is no contact ID on the placeholder list of Contacts

and I have tried with /api/v2/contacts/{{id}} and /api/v2/contacts/[id]

Neither of them delete the contact. What is the correct placeholder for the ID of the contact?

Thank you
