Delete contact from Database via API

Hi,

I'm trying to delete a contact from a database via the API. I can successfully retrieve a row through the API (python code example below), but I can't see how to delete it. replacing the get with delete doesn't work

uri = 'https://api-campaign-eu-1.goacoustic.com/rest/databases/{dbcode}/contacts?filter=keyFields=authorid={authorid}'
response = requests.get(uri,headers=headers)
response.json()

Cheers

Dave
