Is there a way I can initiate a dashboard refresh from a VF page remotely?
Is there an action or a URL I can use to refresh a specified dashboard?
I want to recreate the refresh dashboard button on my VF page. I have seen the schedule refresh option but I am looking for more control for the user to refresh the dashboard on demand.
Salesforce allows you to do this through the Reports and Dashboards REST API
If you make an http PUT request to: BaseURL/services/data/v31.0/analytics/dashboards/DashboardID and set the session id in the request header, it will refresh the dashboard for you.
In a Visualforce page, you could add a method to your controller similar to the following:
public void refreshDashboard(){
HttpRequest req = new HttpRequest();
req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionId());
req.setMethod('PUT');
req.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm() + '/services/data/v35.0/analytics/dashboards/01Z90000000A7Nx');
Http http = new Http();
HttpResponse res = http.send(req);
}
You can't through salesforce or a url param, but you could make a quick java(or language of choice) program to login and do it with a library like phantomjs.
