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.
sfn_start_execution(stateMachineArn, name, input, traceHeader)[required] The Amazon Resource Name (ARN) of the state machine to execute.
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 \_.
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.
Passes the AWS X-Ray trace header. The trace header can also be passed in the request payload.
