Amazonka.StepFunctions.StartExecution
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.
Synopsis
- data StartExecution = StartExecution' {}
- newStartExecution :: Text -> StartExecution
- startExecution_input :: Lens' StartExecution (Maybe Text)
- startExecution_name :: Lens' StartExecution (Maybe Text)
- startExecution_traceHeader :: Lens' StartExecution (Maybe Text)
- startExecution_stateMachineArn :: Lens' StartExecution Text
- data StartExecutionResponse = StartExecutionResponse' {
- httpStatus :: Int
- executionArn :: Text
- startDate :: POSIX
- newStartExecutionResponse :: Int -> Text -> UTCTime -> StartExecutionResponse
- startExecutionResponse_httpStatus :: Lens' StartExecutionResponse Int
- startExecutionResponse_executionArn :: Lens' StartExecutionResponse Text
- startExecutionResponse_startDate :: Lens' StartExecutionResponse UTCTime
Creating a Request
data StartExecution Source #
See: newStartExecution smart constructor.
Constructors

Fields

Instances
Arguments
| :: Text | |
| -> StartExecution |
Create a value of StartExecution with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:input:StartExecution', startExecution_input - 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.
$sel:name:StartExecution', startExecution_name - 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 _.
$sel:traceHeader:StartExecution', startExecution_traceHeader - Passes the AWS X-Ray trace header. The trace header can also be passed
in the request payload.
$sel:stateMachineArn:StartExecution', startExecution_stateMachineArn - The Amazon Resource Name (ARN) of the state machine to execute.
