I have been able to use awscli to get start the execution but I need to be able to know when is completed or result is success before it can go to the next step in the pipeline.
aws stepfunctions start-execution --state-machine-arn arn:aws:states:us-west-2:2xx244xxxx:stateMachine:SamplePipeOrchestration-ftpiles --name SamplePipeOrchestration-ftpiles --input {} --region us-west-2 --profile sampledev
