# Open WebUI Events Example
Send status updates and UI events to Open WebUI during streaming, and optionally intercept tool calls for richer feedback.
## Where is the code?
- Event examples: [open_webui_agent_events](https://github.com/deepset-ai/hayhooks/tree/main/examples/pipeline_wrappers/open_webui_agent_events), [open_webui_agent_on_tool_calls](https://github.com/deepset-ai/hayhooks/tree/main/examples/pipeline_wrappers/open_webui_agent_on_tool_calls)
- See the main docs → Open WebUI integration and event hooks
## Deploy (example)
```bash
hayhooks pipeline deploy-files -n agent_events examples/pipeline_wrappers/open_webui_agent_events
```
## Run
- OpenAI-compatible chat (events stream to Open WebUI):
```bash
curl -X POST http://localhost:1416/v1/chat/completions \
-H 'Content-Type: application/json' \
-d '{
"model": "agent_events",
"messages": [{"role": "user", "content": "Tell me about machine learning"}]
}'
```
!!! tip "Working with Events"
- Use helpers from `hayhooks.open_webui`: `create_status_event`, `create_message_event`, `create_replace_event`, `create_source_event`, `create_notification_event`, `create_details_tag`
- Intercept tool calls via `on_tool_call_start`/`on_tool_call_end` with `streaming_generator`/`async_streaming_generator`
- For recommended Open WebUI settings, see the [Open WebUI Integration](../features/openwebui-integration.md) guide
