Hi there,
I want to do an insert into one of my big tables but I am sure what the template is expected to be.
Do I just pass the rows as an array type?
It depends on the operation you are doing on the table. Based on your screenshot it looks like you are trying to do Tabledata: Insert All, and what you have pasted in the JSON Template body is a schema copied from Google’s documentation.
You can find the expected syntax for the node, which matches Google’s, in Losant’s documentation for the node and operation.
