Looping through the body of a webhook

Very new user here…

My webhook returns data that was uploaded to CSVBox.io. I’ve added a Google Sheet, but now need to loop through the info from the webhook body and add each as a new row in my Sheet. In the screenshot below, this should add 5 rows to my Sheet.

How do I go about looping through the webhook body?

I found this fix, and am working through it now. This should do what I’m looking for.
