📘 Note

On the first page load on which the microsnippet executes, this will only affect tracking (logx), and not experiment activation or evaluation. On subsequent payloads, the user will not get bucketed into any experiments.

If the Dynamic Websites project setting is on, using this API may also affect some experiment activation and evaluation on the first page load.
:::

```javascript
window.optimizelyEdge.push(optOut);
```

```javascript
window.optimizelyEdge.push({
  "type": "optOut",
  "isOptOut": true
});
```

📘 Verify opt-out mode is working

Setting `isOptOut` to `true` creates a cookie called `optimizelyOptOut`.

To verify it is working, you can:

:::Paragraph{listStyleType="disc" indent="1"}
Check for the existence of the `optimizelyOptOut` cookie.
:::

:::Paragraph{listStyleType="disc" listStart="2" indent="1"}
Append the `optimizely_log=DEBUG` query parameter. This prints the Optimizely Performance Edge log which shows if opt-out mode is activated.
