In case you are using the django framework, you should request.body, as post data will remain empty.

def webhook_response(request):
   # it will print the contents from facebook webhook response
   print(request.body)

   # something like the following object will print up if you are using leadgen
   {"object": "page", "entry": [{"id": "0", "time": 111111111, "changes": [{"field": "leadgen", "value": {"ad_id": "444444444", "form_id": "444444444444", "leadgen_id": "444444444444", "created_time": 11111111, "page_id": "444444444444", "adgroup_id": "44444444444"}}]}]}
