How can I start a Webflow interaction using custom JS code with only the data-w-id?

To start a Webflow interaction using custom JS code with just the `data-w-id`, you can utilize the Webflow JavaScript API. Here's a step-by-step guide on how you can achieve this:

1. Locate the element with the desired `data-w-id` attribute in your project's HTML structure.
2. Initialize the Webflow JavaScript API by placing the following code in the `` section of your site's HTML file or within an external JS file:
```javascript

```
3. Inside the callback function, you can use the `Webflow.require()` method to access the Webflow API and perform various actions. You can retrieve the element with the specified `data-w-id` using the `Webflow.require('ix2').$('your-data-w-id')` syntax.
4. Once you have access to the element, you can trigger an interaction using the `startInteraction()` method. For example, if you want to start the "fade-in" interaction, you would use:
```javascript
Webflow.require('ix2').$('your-data-w-id').startInteraction('fade-in');
```
Replace `'your-data-w-id'` with the actual value of your `data-w-id` attribute.
5. Save the changes and refresh your site to see the interaction triggered.

Remember to ensure that the specified `data-w-id` attribute is valid and corresponds to an element with an associated Webflow interaction. You can find the `data-w-id` attribute by inspecting the element in the browser's developer tools or using the Webflow Designer.

Additionally, keep in mind that Webflow interactions are dependent on the Webflow runtime, so make sure it is loaded before attempting to trigger any interactions programmatically.

By following these steps, you should be able to start a Webflow interaction using custom JS code with only the `data-w-id`.
