How to invoke an AWS Step Function using an GET API Gateway

How do I invoke an AWS Step Function using an API Gateway GET request, and the request's JSON payload to the Step Function?

I need the API Gateway to start a Step Function which then invokes a Lambda function that uses the URL input parameter 'pk'.

I have tried this by adding a mapping template within the integration request section. It looks like this:

{
    "input": {
        "pk": "$input.params('pk')"
    }
    "stateMachineArn": "arn:aws:states:eu-central-1:............"
}

I suggest you check out Serverlessland and specifically the Workflows Collection. Lots of awesome examples! You can filter by service to show examples that involve API Gateway. Here's a specific example that might be helpful for you.

There's also a module in the Step Functions Workshop that covers this topic.

Hope this helps!
