# ListSteps
<a name="API_ListSteps"></a>

Provides a list of steps for the cluster in reverse order unless you specify `stepIds` with the request or filter by `StepStates`. You can specify a maximum of 10 `stepIDs`. The AWS CLI automatically paginates results to return a list greater than 50 steps. To return more than 50 steps using the AWS CLI, specify a `Marker`, which is a pagination token that indicates the next set of steps to retrieve.

## Request Syntax
<a name="API_ListSteps_RequestSyntax"></a>

```
{
   "ClusterId": "string",
   "Marker": "string",
   "StepIds": [ "string" ],
   "StepStates": [ "string" ]
}
```

## Request Parameters
<a name="API_ListSteps_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [ClusterId](#API_ListSteps_RequestSyntax) **   <a name="EMR-ListSteps-request-ClusterId"></a>
The identifier of the cluster for which to list the steps.  
Type: String  
Length Constraints: Maximum length of 256.  
Required: Yes

 ** [Marker](#API_ListSteps_RequestSyntax) **   <a name="EMR-ListSteps-request-Marker"></a>
The maximum number of steps that a single `ListSteps` action returns is 50. To return a longer list of steps, use multiple `ListSteps` actions along with the `Marker` parameter, which is a pagination token that indicates the next set of results to retrieve.  
Type: String  
Required: No

 ** [StepIds](#API_ListSteps_RequestSyntax) **   <a name="EMR-ListSteps-request-StepIds"></a>
The filter to limit the step list based on the identifier of the steps. You can specify a maximum of ten Step IDs. The character constraint applies to the overall length of the array.  
Type: Array of strings  
Length Constraints: Minimum length of 0. Maximum length of 10280.  
Pattern: `[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\r\n\t]*`   
Required: No

 ** [StepStates](#API_ListSteps_RequestSyntax) **   <a name="EMR-ListSteps-request-StepStates"></a>
The filter to limit the step list based on certain states.  
Type: Array of strings  
Valid Values: `PENDING | CANCEL_PENDING | RUNNING | COMPLETED | CANCELLED | FAILED | INTERRUPTED`   
Required: No

## Response Elements
<a name="API_ListSteps_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [Marker](#API_ListSteps_ResponseSyntax) **   <a name="EMR-ListSteps-response-Marker"></a>
The maximum number of steps that a single `ListSteps` action returns is 50. To return a longer list of steps, use multiple `ListSteps` actions along with the `Marker` parameter, which is a pagination token that indicates the next set of results to retrieve.  
Type: String

 ** [Steps](#API_ListSteps_ResponseSyntax) **   <a name="EMR-ListSteps-response-Steps"></a>
The filtered list of steps for the cluster.  
Type: Array of [StepSummary](API_StepSummary.md) objects
