StartExecution of statemachines through API Gateway

[msl-kabo]

It would be really good to have the ability to start execution of a statemachine by calling a url.

https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-api-gateway.html

Suggestion for how it could look in serverless.yml

stepFunctions:
  stateMachines:
    myStateMachine:
      events:
        - http:
          method: GET
          path: executeMyStateMachine

Is there any movement on 0.5.0?

@ShaunEgan
Thank you for the pinging!
The plan is not set yet.

I am considering sending a PR to be included into the core at this timing. Because CloudFormation got supported to Step Functions.
serverless/serverless#3024

[ShaunEgan]

Out of curiosity:

I read discussion that step-functions might not make it into core since they are too AWS specific? Would it not be better to get them in here and keep this the defacto plugin for step functions?

I would love to have this functionality available here, I am currently building a project which leans on this plugin and would love to have one place to build my step functions and gateway for them.

Either way, I am happy.

is there a way around this till this feature is supported? I'm building something serverless and would love to be able to trigger the state machine from API Gateway without manually doing it.

[ShaunEgan]

Not without building it through cloudformation or doing it manually. As far as I am aware, this is coming really soon.

Thank you for the comment @ezjacob-maheim and helping @ShaunEgan 😄
Actually the feature will be supported on next release(v1.0). Then I have finished to implement on
the head of v1.0 branch.

If you need this feature before next release, you can build Lambda function to trigger a statemachine.

This should be closed by #33 now 😄
