Conversions Not Increasing

When I send a webhook to the API, all the data comes through but the conversions are not increasing in the dashboard. So, if I sent the example webhook below through I would get all data and it would show up as a lead but the conversion rate should increase however it is not. Is this a bug or a feature?

{
“conversion”: true,
“visitor_id”: “127.0.0.123543254378923893”,
“form_submission”: {
“variant_id”: “a”,
“submitter_ip”: “127.0.0.1”,
“form_data”: {
“first_name”: “John”,
“last_name”: “Doe”,
“email”: “jqdoe@unbounce.com
}
}
}
