PowerBI Embedded: Embed Token Expiration?

Hi there,

 

simple question: PowerBI embedded embed tokens require to specify a time span for validity of the tokens. What is the best practice for the time span - eg. can I simply set the validity (exp: claim in JWT token) to large values like +8 hours to minimize issues with expiring tokens? How can an application embedding PowerBI embedded react to expired tokens? Currently when a token expires I seem to just get a "content is not available" from PowerBI. Any insights are highly welcome.

 

Cheers

Daniel

      Well you can set the expiration span as it's described here: https://azure.microsoft.com/en-us/documentation/articles/power-bi-embedded-app-token-flow/ (search for exp). But my question is more about best practices around how the embedding application can catch a situation where the report embed token has already expired and must be refreshed. Currently when you hit a dashboard where the token has already expired it just shows ugly errors.

      Thanks

      Daniel

        daniel12  did you find out a way to prevent the ugly errors?  Here's what my embedded site looks like after a short time (sometimes 3 minutes--sometimes somewhat longer) if I select a new report tab.  Spectacularly awful, no?  Any ideas here?

    It is normally best to keep the token as short as needed. One hour is usually standard. This is just in case the tokens happen to leak out. There are good reasons why you may want to make them longer; 2 - 8+ hours. It really depends on the scenario and how much of a risk long lived tokens would be for you.

    I am using the example from Github 'Embed for your customers' - .Net Core version.

     

    Is it possible to renew the token and apply it to the report without having to reload the whole page, using JavaScript running in an ASP.Net Core website with an iFrame containg the report?

        Thanks for the reply.

         

        I have looked at this article, but the getNewUserAccessToken(reportId, groupId) doesn't appear to be accessible.  An error message indicating that the funtion doesn't exist is displayed in the console.  

        Is there a link which I should be including for a reference to that funtion?
