You want to POST lead with contact data but ContactFirstName and ContactLastName cannot be updated.

Payload:

{
"AccountPartyID": "XXX",
"ContactFirstName": "XXX",
"ContactLastName": "XXX",
"Name": "XXX",
"OriginTypeCode": "XXX",
"OriginTypeCodeText": "XXX",
"OwnerPartyID": "XXX"
}

Contact field is blank in the created Lead

The cause of the issue might be that you want to create a lead with Active Account (exsiting account) and Inactive Contact (contact does not exist). The scenario is not supported in lead creation via LEADS OWL > New and also OData API.

You should create a lead with valid use cases:

Option 1) with Active Account and Active Contact

{
"AccountPartyID": "XXX",
"ContactID": "XXX",  (existing contact)
"Name": "XXX",
"OriginTypeCode": "XXX",
"OriginTypeCodeText": "XXX",
"OwnerPartyID": "XXX"
}

Option 2) with Inactive Account and Inactive Contact (like in UI you enter company name, contact first / last name)

{
"Company ": "XXX",
"ContactFirstName": "XXX",
"ContactLastName": "XXX",
"Name": "XXX",
"OriginTypeCode": "XXX",
"OriginTypeCodeText": "XXX",
"OwnerPartyID": "XXX"

}
