Synopsis

Calls the AWS Step Functions StartExecution API operation.

Syntax

Start-SFNExecution
-StateMachineArn <String>
-Input <String>
-Name <String>
-TraceHeader <String>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Starts a state machine execution. StartExecution is idempotent. If StartExecution is called with the same name and input as a running execution, the call will succeed and return the same response as the original request. If the execution is closed or if the input is different, it will return a 400 ExecutionAlreadyExists error. Names can be reused after 90 days.

Parameters

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Input <String>
The string that contains the JSON input data for the execution, for example:"input": "{\"first_name\" : \"test\"}"If you don't include any JSON input data, you still must include the two braces, for example: "input": "{}"Length constraints apply to the payload size, and are expressed as bytes in UTF-8 encoding.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Name <String>
The name of the execution. This name must be unique for your AWS account, region, and state machine for 90 days. For more information, see Limits Related to State Machine Executions in the AWS Step Functions Developer Guide.A name must not contain:
  • white space
  • brackets < > { } [ ]
  • wildcard characters ? *
  • special characters " # % \ ^ | ~ ` $ & , ; : /
  • control characters (U+0000-001F, U+007F-009F)
To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the StateMachineArn parameter. The -PassThru parameter is deprecated, use -Select '^StateMachineArn' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.StepFunctions.Model.StartExecutionResponse). Specifying the name of a property of type Amazon.StepFunctions.Model.StartExecutionResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-StateMachineArn <String>
The Amazon Resource Name (ARN) of the state machine to execute.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-TraceHeader <String>
Passes the AWS X-Ray trace header. The trace header can also be passed in the request payload.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named

AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile.

This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
