# Piggyback scripts

HockeyStack can detect and piggyback on a number of third‑party embeds and load the corresponding helper script. Below is everything you need to know.

### Scripts Loading Conditions

HockeyStack automatically loads additional “piggyback” integrations when it detects you’re using one of the following on your page:

| Integration       | Detection Logic                                                  |
| ----------------- | ---------------------------------------------------------------- |
| **Arcade**        | `iframe[src*="demo.arcade.software"]`                            |
| **Heyflow**       | `script[src*="heyflow.app"]`                                     |
| **6Sense**        | `script[src*="j.6sc.co/6si.min.js"]`                             |
| **Demandbase**    | `script[src*="tag.demandbase.com"]`                              |
| **Calendly**      | `URLSearchParams(window.location.search).get('event_type_uuid')` |
| **Qualified**     | `script[src*="qualified"]`                                       |
| **ZoomInfo Chat** | `script[src*="insent.ai"]`                                       |
| **Navattic**      | `script[src*="js.navattic.com"]`                                 |
| **Drift**         | `script[src*="js.driftt.com"]`                                   |
| **Marketo Forms** | `window.MktoForms2`                                              |
| **Pardot**        | `script[src*="pi.pardot.com"]`                                   |

### How it works:

On DOM ready (or once the page `load` event fires), `loadScripts()` checks each of the above conditions and, if met, appends the corresponding `<script>` tag to `<head>`. It will retry up to 50 times (with 200 ms intervals) to catch any late‑loaded embeds.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.hockeystack.com/technical-details/tracking/piggyback-scripts.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
