Power BI SDK for .NET: Service Code Retry Handling

nelsonnyland — Thu, 22 May 2025 16:01:09 GMT

I have a .NET 8 app connecting to Power BI API using the provided SDK nuget package (Microsoft.PowerBI.Api).

Is there a provided retry handler for bad service codes?

Thank you.

Hi @nelsonnyland ,

Thank you for reaching out to Microsoft Fabric Community Forum.

Any GET request made to a API endpoint may return an HTTP redirect (301 or 302). Clients should gracefully handle such redirects by observing the Location header and issuing a subsequent GET. Documentation concerning specific endpoints will not explicitly call out where redirects may be used.

In the case of a 500-level status code, the client can implement a reasonable retry mechanism. The official NuGet client retries three times when encountering any 500-level status code or TCP/DNS error.

Hi Manikanteswara,

It looks like there is some misunderstanding. I am looking for information regarding (Microsoft.PowerBI.Api). This is not a .NET Graph SDK, and as far as I know this is not a NuGet Server API. I have not been able to find any documentation specifically about the Power BI SDK that states whether it has a retry mechanism. Given that the .NET Graph SDK comes with retry handling, I would not be surprised if that was indeed the case.

Thank you for the follow-up, you're absolutely right to clarify that Microsoft.PowerBI.Api is not part of the .NET Graph SDK or a NuGet server API.The Power BI .NET SDK (Microsoft.PowerBI.Api) does not have built-in retry logic.

Unlike the Graph SDK, which includes a built-in retry handler for throttling (like 429s or 5xx errors), the Power BI SDK is a more lightweight wrapper over the REST API. That means you’ll need to implement your own retry mechanism if you want to handle transient faults or throttling scenarios.

A common approach is to use a library like Polly to define a retry policy. Here’s an example of how that might look in C#:

var retryPolicy = Policy
    .Handle<HttpRequestException>()
    .OrResult<HttpResponseMessage>(r =>
        (int)r.StatusCode == 429 || (int)r.StatusCode >= 500)
    .WaitAndRetryAsync(3, retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)));

var result = await retryPolicy.ExecuteAsync(() =>
powerBIClient.Reports.GetReportInGroupAsync(groupId, reportId));
