# SendPipelineExecutionStepFailure
<a name="API_SendPipelineExecutionStepFailure"></a>

Notifies the pipeline that the execution of a callback step failed, along with a message describing why. When a callback step is run, the pipeline generates a callback token and includes the token in a message sent to Amazon Simple Queue Service (Amazon SQS).

## Request Syntax

```
{
   "CallbackToken": "string",
   "ClientRequestToken": "string",
   "FailureReason": "string"
}

## Request Parameters
<a name="API_SendPipelineExecutionStepFailure_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.

 ** [CallbackToken](#API_SendPipelineExecutionStepFailure_RequestSyntax) **   <a name="sagemaker-SendPipelineExecutionStepFailure-request-CallbackToken"></a>
The pipeline generated token from the Amazon SQS queue.  
Type: String  
Length Constraints: Fixed length of 10.  
Pattern: `[a-zA-Z0-9]+`   
Required: Yes

 ** [ClientRequestToken](#API_SendPipelineExecutionStepFailure_RequestSyntax) **   <a name="sagemaker-SendPipelineExecutionStepFailure-request-ClientRequestToken"></a>

## Response Syntax
<a name="API_SendPipelineExecutionStepFailure_ResponseSyntax"></a>

```
{
   "PipelineExecutionArn": "string"
}
```

## Response Elements
<a name="API_SendPipelineExecutionStepFailure_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.

 ** [PipelineExecutionArn](#API_SendPipelineExecutionStepFailure_ResponseSyntax) **   <a name="sagemaker-SendPipelineExecutionStepFailure-response-PipelineExecutionArn"></a>
The Amazon Resource Name (ARN) of the pipeline execution.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 2048.  
Pattern: `arn:aws[a-z\-]*:sagemaker:[a-z0-9\-]*:[0-9]{12}:pipeline\/.*\/execution\/.*`
