• sfn.stop_execution

List State Machines (sfn.list_state_machines)

Lists the existing state machines.

kind = "sfn.list_state_machines"

Start Execution (sfn.start_execution)

Starts a state machine execution.

Configuration ([sfn])

Field	Type	Required	Description
state_machine_arn	string	Yes	The Amazon Resource Name (ARN) of the state machine to execute.
name	string	No	The name of the execution.

The input for the execution is taken from the [payload] block (either data or file).

Example

version = "1.0"
kind = "sfn.start_execution"

[sfn]
state_machine_arn = "arn:aws:states:us-east-1:123456789012:stateMachine:MyStateMachine"
name = "test-execution-1"

[payload]
data = """
{
  "input_key": "input_value"
}
"""

Describe Execution (sfn.describe_execution)

Describes an execution.

Configuration ([sfn])

Field	Type	Required	Description

Stops an execution.

Configuration ([sfn])

Field	Type	Required	Description
execution_arn	string	Yes	The Amazon Resource Name (ARN) of the execution to stop.
error	string	No	The error code of the failure.

Example

version = "1.0"
kind = "sfn.stop_execution"
