[API] Create contact with account details when creating a ticket

[API] Create contact with account details when creating a ticket

Dear all,

When creating a ticket through API we can set Contact Details, it creates the ticket and the contact (if the latter do not exist). However when I add accountId in the contact section it fails with the following error:
{
  errorCode: 'UNPROCESSABLE_ENTITY',
  message: "An extra parameter 'accountId' is found"
}
The same happens when I add title attribute.
My question is then how can we create (update if it exists) both the Account and the Contact when creating a new ticket?

Thanks,
Regards
