WHD - Adding a note via API

We have an API that runs through a table of tickets and changes the Status Type ID. I would like to add a note at the same time but am having trouble making the syntax work.

The table is identified from a SQL query and the syntax to change the status is:

{"statustype":{"type":"StatusType","id":3}}

I am assuming I can add to this syntax string, or create a separate one, that will add a note but so far I am not having any success.

I have tried variations of:

{"noteText":"Reinstalled the printer driver. Seems to be working fine now.","statustype":{"type":"StatusType","id":3}

What am I missing?
