webhook answers structure changed between 24/03 and 27/03 ?

Hej,

I don’t know what’s going on, I made some tests before today to match the structure of the responses sended by typeform via a webhook, the structure I got was this one : 

{
	"token": "foo",
	"landed_at": "2023-03-24T10:23:04Z",
	"submitted_at": "2023-03-24T10:23:51Z",
	"hidden": {},
	"calculated": {},
	"answers": [],
	"fields": []
}

And today, with the same form, I get this structure :

{
	"event_id": "foo",
	"event_type": "form_response",
	"form_response": {
		"form_id": "foo",
		"token": "bar",
		"landed_at": "2023-03-27T08:47:40Z",
		"submitted_at": "2023-03-27T08:48:11Z",
		"hidden": {},
		"calculated": {},
		"variables": [],
		"definition": {},
		"answers": [],
		"ending": {}
	}
}

Can anyone explain me what I’m doing wwrong please ? We didn’t change anything…

Regards,
