Hii prasaddn 

 

There is no free, out-of-the-box Power BI custom visual that can securely call an external backend API and render dynamic text summaries in an Embed for your customers (.NET / app-owns-data) scenario. Due to sandboxing and security restrictions, custom visuals cannot freely make arbitrary API calls unless they are purpose-built and certified, and most AppSource visuals don’t support this pattern. In practice, the supported approaches are to build your own custom visual that calls a controlled API endpoint, or move the summarization logic outside Power BI (Azure Function/Fabric/Databricks) and load the results into the model for display using standard visuals.

Thank you again rohit1991 for sharing your expertise on this. Let me see what best I can do. The last option is to pre-compute and summarize comments for various dimension of filter selections. Thank you again for your time.

    Hi prasaddn ,
    Thanks for confirming. Given the current limitations with Power BI Embedded, pre computing or periodically refreshing the summarized results outside Power BI and then displaying them using standard visuals is the most reliable and supported approach in a .NET embedded setup. Glad the discussion helped bring clarity on the available options.
