Hi there ,
I’m building an IoT App, and I’m using a custom input trigger. Each time that a device send data, we should create a new item (service requests).
My custom input trigger looks like this:
And works well (tested with postman, 200 received,

Subscribe / unsubscribe is OK.
I’m trying to create an new item based on the output fields of this custom trigger. And I failed…
First try: with the action "Create an Item"
I tried with a Item Column Values field, but I don’t know which format is required. I tried this:
I receive a 200, but nothing happens.
Action trigger looks like this:
Is there a doc somewhere to know the format of itemColumnValues?
Second try: with the action "Create an Item with mapping"
Looks really promising (at least the title), but then, I’m lost:
Same question: is there a doc somewhere or codes example?
