It should be real time, check the first paragraph at What can developers do with Power BI? And I don't notice some latency when embeding report via Power BI REST API.
Hi, i want to use Power BI REST API to get reports on my account and show them on my web app. My doubt is:
When a user access to my app and see the iframe with report obtained by C# code, will it be real time data? What i mean is... will iframe data stay cached 1 hour like "publish to web" option or it'll always be real time access to data and info on report?
By the way, the user can't access the report unless the user has access to your report in Power BI Service.
