Starts an execution of the workflow type in the specified domain using
the provided workflowId
and input data.
This action returns the newly started workflow execution.
Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
- Use a
Resource
element with the domain name to limit the action to only specified domains. - Use an
Action
element to allow or deny permission to call this action. - Constrain the following parameters by using a
Condition
element with the appropriate keys. - 'tagList.member.0': The key is 'swf:tagList.member.0'.
- 'tagList.member.1': The key is 'swf:tagList.member.1'.
- 'tagList.member.2': The key is 'swf:tagList.member.2'.
- 'tagList.member.3': The key is 'swf:tagList.member.3'.
- 'tagList.member.4': The key is 'swf:tagList.member.4'.
taskList
: String constraint. The key is 'swf:taskList.name'.- 'workflowType.name': String constraint. The key is 'swf:workflowType.name'.
- 'workflowType.version': String constraint. The key is 'swf:workflowType.version'.
If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

Creating a Request
startWorkflowExecution Source #
Creates a value of StartWorkflowExecution
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data StartWorkflowExecution Source #
See: startWorkflowExecution
smart constructor.
Request Lenses
sTagList :: Lens' StartWorkflowExecution [Text] Source #
The list of tags to associate with the workflow execution. You can specify a maximum of 5 tags. You can list workflow executions with a specific tag by calling ListOpenWorkflowExecutions or ListClosedWorkflowExecutions and specifying a TagFilter.
sTaskStartToCloseTimeout :: Lens' StartWorkflowExecution (Maybe Text) Source #
Specifies the maximum duration of decision tasks for this workflow
execution. This parameter overrides the defaultTaskStartToCloseTimout
specified when registering the workflow type using
RegisterWorkflowType.
The duration is specified in seconds; an integer greater than or equal to 0. The value "NONE" can be used to specify unlimited duration.
A task start-to-close timeout for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task start-to-close timeout was specified at registration time then a fault will be returned.
sLambdaRole :: Lens' StartWorkflowExecution (Maybe Text) Source #
The ARN of an IAM role that authorizes Amazon SWF to invoke AWS Lambda functions.
In order for this workflow execution to invoke AWS Lambda functions, an appropriate IAM role must be specified either as a default for the workflow type or through this field.
sInput :: Lens' StartWorkflowExecution (Maybe Text) Source #
The input for the workflow execution. This is a free form string which
should be meaningful to the workflow you are starting. This input
is
made available to the new workflow execution in the
WorkflowExecutionStarted
history event.
sExecutionStartToCloseTimeout :: Lens' StartWorkflowExecution (Maybe Text) Source #
The total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the workflow type.
The duration is specified in seconds; an integer greater than or equal to 0. Exceeding this limit will cause the workflow execution to time out. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of "NONE" for this timeout; there is a one-year max limit on the time that a workflow execution can run.
An execution start-to-close timeout must be specified either through this parameter or as a default when the workflow type is registered. If neither this parameter nor a default execution start-to-close timeout is specified, a fault is returned.
sTaskList :: Lens' StartWorkflowExecution (Maybe TaskList) Source #
The task list to use for the decision tasks generated for this workflow
execution. This overrides the defaultTaskList
specified when
registering the workflow type.
A task list for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task list was specified at registration time then a fault will be returned.
The specified string must not start or end with whitespace. It must not
contain a :
(colon), \/
(slash), '|' (vertical bar), or any control
characters (\u0000-\u001f | \u007f - \u009f). Also, it must not
contain the literal string quotarnquot.
sTaskPriority :: Lens' StartWorkflowExecution (Maybe Text) Source #
The task priority to use for this workflow execution. This will override
any default priority that was assigned when the workflow type was
registered. If not set, then the default task priority for the workflow
type will be used. Valid values are integers that range from Java's
MIN_VALUE
(-2147483648) to MAX_VALUE
(2147483647).
Higher numbers indicate higher priority.
For more information about setting task priority, see Setting Task Priority in the Amazon Simple Workflow Developer Guide.
sChildPolicy :: Lens' StartWorkflowExecution (Maybe ChildPolicy) Source #
If set, specifies the policy to use for the child workflow executions of this workflow execution if it is terminated, by calling the TerminateWorkflowExecution action explicitly or due to an expired timeout. This policy overrides the default child policy specified when registering the workflow type using RegisterWorkflowType.
The supported child policies are:
- TERMINATE: the child executions will be terminated.
- REQUEST_CANCEL: a request to cancel will be attempted for each
child execution by recording a
WorkflowExecutionCancelRequested
event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event. - ABANDON: no action will be taken. The child executions will continue to run.
A child policy for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default child policy was specified at registration time then a fault will be returned.
sDomain :: Lens' StartWorkflowExecution Text Source #
The name of the domain in which the workflow execution is created.
sWorkflowId :: Lens' StartWorkflowExecution Text Source #
The user defined identifier associated with the workflow execution. You
can use this to associate a custom identifier with the workflow
execution. You may specify the same identifier if a workflow execution
is logically a restart of a previous execution. You cannot have two
open workflow executions with the same workflowId
at the same time.
The specified string must not start or end with whitespace. It must not
contain a :
(colon), \/
(slash), '|' (vertical bar), or any control
characters (\u0000-\u001f | \u007f - \u009f). Also, it must not
contain the literal string quotarnquot.
sWorkflowType :: Lens' StartWorkflowExecution WorkflowType Source #
The type of the workflow to start.
Destructuring the Response
startWorkflowExecutionResponse Source #
Creates a value of StartWorkflowExecutionResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data StartWorkflowExecutionResponse Source #
Specifies the runId
of a workflow execution.
See: startWorkflowExecutionResponse
smart constructor.
Response Lenses
swersRunId :: Lens' StartWorkflowExecutionResponse (Maybe Text) Source #
The runId
of a workflow execution. This ID is generated by the service
and can be used to uniquely identify the workflow execution within a
domain.
swersResponseStatus :: Lens' StartWorkflowExecutionResponse Int Source #
The response status code.
