Path variables in AWS Step Function

I'm trying to figure out a way to pass path variables in aws step functions for api gateway invocation. I was able to pass query parameters as shown here:- https://docs.aws.amazon.com/step-functions/latest/dg/connect-api-gateway.html

How do i pass path variables?

Edit 1: Adding more info : how do i pass path variable which i receive in the response from previous step ?

Solution

Just specify the full path string in Path. For example (other attributes are hidden for clarity):

{
    "Type": "Task", 
    "Resource":"arn:aws:states:::apigateway:invoke", 
    "Parameters": {
        "ApiEndpoint": "example.execute-api.us-east-1.amazonaws.com",
        "Path": "pet/5",
        ...
}

This will invoke:

example.execute-api.us-east-1.amazonaws.com/pet/5

So that if you have configured your resource path as

/pet/{pet_id}

The value of path parameter pet_id will be 5.

EDIT

Since OP explained the need to loop and call the API with different ID values, suggest to create a custom Lambda, and custom code the logic to loop through each ID and call the API. Or, you can code the loop to occur in the workflow itself. See https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-create-iterate-pattern-section.html.
