# Example 4 - Node with Timeout Error Code & Error Message (HTTP)

This example demonstrates how to customize timeout handling in FlowSync transactions. The configuration extends [Example 1 - Node with Transaction Mode (HTTP)](https://docs.cybus.io/2-0-6/documentation/services/flowsync/flowsync-example-1) by demonstrating how to define specific timeout behavior, including custom timeout duration, error codes, and error messages. When a request does not receive a response within the specified timeout period, the system returns a configured HTTP 408 error along with a custom message, providing a better user experience for timeout scenarios.

* To call the HttpNode in the example below, run the following command:

{% code lineNumbers="true" %}

```yaml
curl --insecure \
--location 'https://127.0.0.1/data/flowsync/example4' \
--header 'Authorization: Bearer <replace with your token>'
```

{% endcode %}
