Hi DiKi-I ,
Thanks for raising this – there’s been some confusion around User Data Functions in Fabric, especially since they’re still in preview and not fully rolled out in all environments.
A few things to check:
Feature Availability
- Make sure your workspace is on a supported Fabric capacity (F64 or higher).
- UDFs are still in private preview for some tenants, so they might not appear in the UI by default.
Enable the UI Option (Workaround)
- Try appending this to your Fabric URL and refresh the page:
&ArtifactFunctionSet=1
- This sometimes forces the UI to show the “User Data Function” option under “New Item”.
Use Visual Studio Code (Optional)
- You can also create and manage UDFs using the Microsoft Fabric VS Code extension, which gives more control and visibility.
Known Issues
- There’s a known issue where UDFs don’t show up in the pipeline function activity pane. Microsoft is working on it [1].
Let me know if you’re trying to use UDFs for a specific use case (e.g., calling APIs, transforming data, etc.) – I can help tailor the setup.

I'm able to run udf its just that when I'm testing it with openai its not working.
Good to hear that the UDF itself is running. Regarding the issue with OpenAI, here are a few things to check:
1. Network Access
- Make sure your UDF environment has outbound internet access. Some Fabric environments (especially in secured or restricted tenants) might block external HTTP calls.
2. Authentication
- If you're calling OpenAI’s API, ensure you're passing the correct API key in the header:
Authorization: Bearer YOUR_API_KEY
- Also double-check the endpoint URL (e.g., https://api.openai.com/v1/completions or chat/completions depending on the model).
3. Timeouts and Payload
- Keep the payload small for testing. Some environments have strict timeout limits for external calls.
- Try a simple prompt first to validate the connection.
4. Error Details
- If you’re getting a specific error message or status code, feel free to share it here. That’ll help narrow it down quickly.
