How to Invoke AWS step function using API gateway?

Question

According to Amazon's documentation, step function can be invoked using HTTP API.

Step Functions can be accessed and used with the Step Functions console, the AWS SDKs, or an HTTP API.

I tried to search the detailed information, but can't seem to find any good ones. Does anyone know how to invoke AWS step function using API gateway, similar to the way it invokes Lambda functions?
