Pass Data to Step Function From HTTP API Gateway

Question

I have a Step Function integration with one of my routes in API Gateway. My API is an HTTP API. It has the following settings:

This is successfully invoking my StepFunction but I am unable to access any of my body parameters. This route is being invoked from a front-end form which submits data. I would like to use this data for further processing in my step functions.

When I see my step function execution, the input is just {}, is there something I need to change?

Answer 1

In the advanced settings set a value for "Input - optional" of "$request.body"
