# Click on the details page

If you want to send product click information, also pass the following parameters in addition to the [general parameters](/integration/tracking-interface/general-parameters.md):

| Parameter  |           | Description                                                                                                                                                                                                                                                                      |
| ---------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `query`    | essential | The search term entered by the user. For a navigation click, send the full category path as the query value.                                                                                                                                                                     |
| `pos`      | essential | The absolute position of the product in the search results. For example, the first product on page 2 is position 11 if each result page contains 10 products. The first product on page 1 is position 1.                                                                         |
| `page`     | essential | The number of the search result page on which the selected product was displayed. The first page has the number 1.                                                                                                                                                               |
| `pageSize` | essential | The number of products per search result page at the time the click was executed.                                                                                                                                                                                                |
| `campaign` | essential | A product contains the field `_FFCampaign_` if it reached the search results through a campaign. This field contains the campaign ID. When the user interacts with that product, send the ID with the `campaign` parameter so the influence of Campaign Manager can be measured. |

## REST

The REST API documentation is part of the search application and is available at \[your NG server]/fact-finder/swagger-ui.html. You can also access it here:

Swagger Link: <https://ng-demo.fact-finder.de/fact-finder/swagger-ui.html>

In addition to the parameter documentation, you can test requests and inspect the results directly. Because the documentation is built with Swagger, you can also use Swagger Codegen to generate a client.

Product click event documentation is available through the `click` method in the `tracking` resource.

## 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.fact-finder.com/integration/tracking-interface/click-on-the-details-page.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.
