# Add Code

Now that you are able to embed the Scene Viewer experience generated and hosted through the console, it's time to inject your own scripts into the webpage.

{% hint style="success" %}
Adding scripts into webAR experiences is only available in the [Custom](mailto:sales@echo3D.com) plan.
{% endhint %}

If you'd like to inject your own JavaScript scripts into the webpage, go back to the console and [add metadata](https://docs.echoar.xyz/web-console/manage-pages/data-page/how-to-add-data#adding-metadata) to add code to the experience. After adding metadata, [relaunch the experience](https://docs.echoar.xyz/scene-viewer/deploy-experience#launching-the-scene-viewer-app).

The following keys are words the system uses as pre-defined metadata keys to control built-in animations:

| Keyword         | Type   | Options                                                       | Description                                                                      |
| --------------- | ------ | ------------------------------------------------------------- | -------------------------------------------------------------------------------- |
| webarScript\<X> | string | Any string that represents a URL to a remote JavaScript file. | The remote URL of a JavaScript code file that will be injected into the webpage. |
| <p>webarOnClick |        |                                                               |                                                                                  |

</p><p>
</p><p></p> | string | Any string that matches a name of an existing function to be called upon click. The function must be followed by brackets `()`, either empty or with arguments. | Runs a specific function when clicking the webpage.                              |

For example:

| Key          | Value                                               |
| ------------ | --------------------------------------------------- |
| webScript1   | <https://code.jquery.com/jquery-3.5.0.js>           |
| webScript2   | <https://www.company.me/path-to-javascript-file.js> |
| webarOnClick | createCache()                                       |

Remember to [relaunch the experience](https://docs.echoar.xyz/scene-viewer/deploy-experience#launching-the-scene-viewer-app) after adding metadata with Scene Viewer experiences for the change to take effect.[<br>](https://docs.echoar.xyz/scene-viewer/deploy-experience)
