Hi, Let me know how to Triggering AWS Step Functions by AWS API Gateway Calls in SST

Hey @Sakar, you mean an Api request directly starts a Step Function execution without going through a Lambda function right?

@Frank Yea, that is what I want. Invoking a State Machine from RestAPI by passing parameters.

Got it! Created an issue here - https://github.com/serverless-stack/serverless-stack/issues/666

@Frank Thank you.

@Frank any update on that? issue on github seems to be laying several months in backlog. How would recommend starting step functions from the ApiGateway if the SST construct is not yet expanded? I am asking about the Express StepFunctions which will get executed and return results to the Api Client. a) via lambda? -> easy, but does not convince me boxing Step Function into lambda and its limits + costs (memory, duration, etc) b) via unboxing apigateway.HttpApi from sst.Api and adding integration to the route there via https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-apigatewayv2.AddRoutesOptions.html? not sure if it possible, did not find enough time to find out working example c) via a separate instance of the API like suggested here: https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-step-functions-rest-api-integration-cdk.html d) use cdk RestAPI construct -> how would replacing sst.Api with RestAPI impact my development expierence? e) anything else? @Sakar how do you run through it?

Hey @Marcin M, it is doable in CDK now as HTTP API just supported AWS service integration - https://github.com/aws/aws-cdk/pull/18154
