Use the Event Inspector to review the information sent to your account from the Optimizely APIs for accuracy. You can also troubleshoot data as it comes into ODP, since data updates result in underlying events.

:::hint{type="info"}
**Note**

Although ODP processes customer and object updates as events, the application does not store these events.

## Access and use the inspector

To access and start the inspector:

1. Go to **Settings** **> Event Inspector**.
2. Click **Start Inspector**. The inspector records your API calls for up to 15 minutes.

3. Click **Refresh** to see the results.

4. Click **Deactivate Inspector** to end the inspector's event collection after refreshing the page and loading the desired timeframe of events. If you see too many records, adjust the number of rows that display using the **Rows** drop-down list.

## Example

JSON-formatted events display:

```javascript
{\\"customer_id\\":\\"12345\\",\\"event_type\\":\\"shop\\",\\"tracker_id\\":\\"yfwfhfhewufkj\\", \\"ts\\":1452177429,\\"ip\\":\\"127.0.0.1\\",\\"ua\\":\\"Mozilla/5.0 (Windows NT 5.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11\\"}
```

## Troubleshoot events

The information coming into Data Core Service (DCS) is often customer-specific. As a result, any testing involves specific internal users acting as customers.

Locate the unique DCS VUID of these test customers to make troubleshooting your events easier:

1. Have the test user visit your website and right-click anywhere on a page.
2. Select **Inspect Element** or **Inspect**.
3. Click **Console**.
4. Input **zaius.VUID** and press enter. 
5. Copy this VUID, remove the hyphens and search for it in the **Event Inspector** using **CMD-F** on Mac or **CTRL-F** on PC.
