Deal created, but fields empty

Hello, I’m using a retool integration to create deals in hubspot, but I’m finding that the fields are empty in hubspot eventhough a get a succesful 200/201 response. Any ideas on what I might need to do on the POST side to be able to add simple fields like dealname, dealstage, etc?

@KVansice this is an example JSON showing how to set the deal name and deal stage, is this how you have it configured?

///Example new deal
{
 "properties": {
 "amount": "7000.00",
 "closedate": "2023-12-12T20:18:00.000Z",
 "dealname": "Jennifer - New Deal",
 "pipeline": "sales",
 "dealstage": "closedwon",
 "hubspot_owner_id": "5773265"
 }
}
