New API Documentation - Developer Preview Available

We are excited to announce the developer preview of our new API documentation for AWS SDK for JavaScript v3. Please follow instructions on the landing page to leave us your feedback.

Class ListOpenWorkflowExecutionsCommandProtected

Returns a list of open workflow executions in the specified domain that meet the filtering criteria. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.

This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.

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.

    • tagFilter.tag: String constraint. The key is swf:tagFilter.tag.

    • typeFilter.name: String constraint. The key is swf:typeFilter.name.

    • typeFilter.version: String constraint. The key is swf:typeFilter.version.

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.


Use a bare-bones client and the command you need to make an API call.

OperationNotPermittedFault (client fault)

Returned when the caller doesn't have sufficient permissions to invoke the action.


UnknownResourceFault (client fault)

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.



Base exception class for all service exceptions from SWF service.
