Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Step Functions is a service that lets you coordinate the components of distributed applications and microservices using visual workflows.

You can use Step Functions to build applications from individual components, each of which performs a discrete function, or task, allowing you to scale and change applications quickly. Step Functions provides a console that helps visualize the components of your application as a series of steps. Step Functions automatically triggers and tracks each step, and retries steps when there are errors, so your application executes predictably and in the right order every time. Step Functions logs the state of each step, so you can quickly diagnose and debug any issues.

Step Functions manages operations and underlying infrastructure to ensure your application is available at any scale. You can run tasks on Amazon Web Services, your own servers, or any system that has access to Amazon Web Services. You can access and use Step Functions using the console, the Amazon Web Services SDKs, or an HTTP API. For more information about Step Functions, see the Step Functions Developer Guide .

If you use the Step Functions API actions using Amazon Web Services SDK integrations, make sure the API actions are in camel case and parameter names are in Pascal case. For example, you could use Step Functions API action startSyncExecution and specify its parameter as StateMachineArn.

Sending a Request Using StepFunctions

var stepfunctions = new AWS.StepFunctions();
stepfunctions.createActivity(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response

Locking the API Version

In order to ensure that the StepFunctions object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var stepfunctions = new AWS.StepFunctions({apiVersion: '2016-11-23'});

You can also set the API version globally in AWS.config.apiVersions using the stepfunctions service identifier:

AWS.config.apiVersions = {
  stepfunctions: '2016-11-23',
  // other service API versions

var stepfunctions = new AWS.StepFunctions();
