Edit table using Appsheet API

So I’m trying something new and I’m hitting the Appsheet API. I think I have most of it working, but sadly it’s not updating my row. Here is my JSON, anyone have an idea why it’s not updating the row?

{
“Action”: “Edit”
},
“Rows”: [
{
“UID”: “021c6fbb”,
“Rep 1 Position”: “Representative”
}
]
}

I believe a “Properties” variable is required in the payload. Just use your locale, like “en-US”.
