Adding custom attribute via api

Questions
1

I am creating some items dynamically and want to add a custom attribute to it. The item gets created, but I can’t seem to ponder out how to set the custom attribute. What is incorrect about this payload for catalog upsert?

I am apparently great at asking the question and then immediately seeing the issue. I have a property incorrectly named.
