### Start an A/B Test

Click the **`Start`** button in the upper right of the detail page for an A/B Test that is in Draft status.\

### When the events set in A/B Test goals are not being received

When you try to start an A/B Test, the following 2 items are checked. If either item is not satisfied, the screen shown below will appear.

Both items must be satisfied for the A/B Test to proceed as intended.

* Whether the A/B Test code is integrated and user identifiers are being sent
* Whether events required to calculate the results of registered goals are being sent

To resolve issues, refer to [Health Check](/en/ab-test/status/health-check.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hackle.io/en/ab-test/create-and-configure/start-ab-test.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
