# Segment

> Stream Usertour events into Segment as they happen.

The Segment integration streams **events out**: every event Usertour tracks arrives as `track` calls on a Segment source in real time, with `messageId` deduplication, ready to fan out to your Segment destinations. See [what gets sent](/integrations/overview#what-gets-sent).

## Connect

Go to **Settings → Integrations → Segment** and follow the [standard connect flow](/integrations/overview#connect-a-provider) with:

* **Credential:** a **Write key** from a Segment *source*. In Segment, click **Add Source**, search for **HTTP API**, and add it (use a dedicated source rather than sharing a write key with other producers); the write key is on the source's settings page under API Keys. Cloud sources don't have write keys — it must be an event-stream source.
* **Data residency:** US or EU, matching where your Segment workspace is hosted.

## Stream events to Segment

Streaming starts with the first save and is controlled by the switch at the top of the page. Delivery, retries, and the message log are described in the [overview](/integrations/overview#delivery-and-reliability).

## Troubleshooting

* **Verify arrivals in the Debugger:** the source's **Debugger** tab in Segment shows events within seconds — the fastest way to confirm the pipe after **Send test event**.
* **Nothing arrives:** confirm the write key comes from an **HTTP API** source (not a cloud source) and that the source is enabled in Segment.
* Everything else: see the [overview troubleshooting](/integrations/overview#troubleshooting).
