Records a WorkflowExecutionSignaled event in the workflow execution
history and creates a decision task for the workflow execution identified by the given domain,
workflowId and runId. The event is recorded with the specified user defined signalName and
input (if provided).
If a runId isn't specified, then the WorkflowExecutionSignaled event is
recorded in the history of the current open workflow with the matching workflowId in the
domain.
If the specified workflow execution isn't open, this method fails with
UnknownResource.
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.
You cannot use an IAM policy to constrain this action's parameters.
If the caller doesn't 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 is set to OPERATION_NOT_PERMITTED.
For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF
Workflows in the Amazon SWF Developer Guide.
Example
Use a bare-bones client and the command you need to make an API call.
Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.
