Access token expires mid-batch in Azure Function using Genesys .NET SDK

Running a batch job in an Azure Function to update conversation attributes for 5,000 records. Using the GenesysCloudPlatform SDK for .NET. The job starts fine, processes about 2,000 items, then fails with 401 Unauthorized.

I’m using OAuthTokenService.GetAccessTokenAsync() at the start of the function execution. The docs say the token is valid for 1 hour. My function timeout is 5 minutes, but the loop takes longer than expected due to rate limiting delays.

Here’s the setup:

  • Azure Function v4 (.NET 6)
  • GenesysCloudPlatform SDK v12.4.0
  • OAuth client credentials flow
  • Loop with Task.Delay(200) to stay under rate limits

The error happens randomly around the 3,000th item. Sometimes it’s sooner.

I’ve tried:

  • Checking token expiration before each API call
  • Using HttpClient with automatic retry
  • Increasing the token cache time

The SDK doesn’t seem to have a built-in token refresh mechanism for long-running jobs. How are you handling this? Do you manually refresh the token every 50 minutes? Or is there a better pattern for batch operations?

Code snippet:

var token = await oauthService.GetAccessTokenAsync();
var client = new GenesysCloudPlatform(token);
foreach (var item in items)
{
 await client.Analytics.PostAnalyticsConversationDetailsQuery(...);
 await Task.Delay(200);
}
