start-execution

Description

Starts a state machine execution.

Note

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.

See 'aws help' for descriptions of global parameters.

Synopsis

  start-execution
--state-machine-arn <value>
[--name <value>]
[--input <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--state-machine-arn (string)

The Amazon Resource Name (ARN) of the state machine to execute.

--name (string)

The name of the execution. This name must be unique for your AWS account and region 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:

  • whitespace
  • brackets `` { } [ ]``
  • wildcard characters ? *
  • special characters " # % \ ^ | ~ ` $ , ; : /
  • control characters (U+0000-001F , U+007F-009F )

--input (string)

The string that contains the JSON input data for the execution, for example:

"input": "{\"first_name\" : \"test\"}"

Note

If you don't include any JSON input data, you still must include the two braces, for example: "input": "{}"

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

executionArn -> (string)

The Amazon Resource Name (ARN) that identifies the execution.

startDate -> (timestamp)

The date the execution is started.
