You can refresh a dashboard by using a PUT Dashboard Results request. Dynamic dashboards can also be refreshed via the REST API.
Use a PUT request on the Dashboard Results resource to trigger a refresh of a dashboard. The refresh response returns the URL of the status resource after the refresh is triggered. If filter parameters are included in the PUT request, only the filtered data will be refreshed. For more information on filtering, see Filter Dashboard Results.
Example Usage
The following PUT request refreshes the dashboard with the ID of 01ZD00000007S89MAE.
