# How to Specify 3D Assets for Link Sharing



## Overview

Using HTML meta tags, you can specify 3D assets to be displayed when a link is shared on Facebook. The process is similar to specifying a flat image.  

## Step-by-Step Instructions

- Collect the link details: **link title**, **3D asset URL**. For details regarding supported formats and limitations, see [3D Asset Requirements](https://developers.facebook.com/docs/sharing/3d-posts/asset-requirements).

- Modify the HTML response header for your URL to include the following meta tags. Replace the content attributes with your information.

```html
<meta property="og:type" content="threed.asset" />
<meta property="og:asset" content="your_3d_asset_url" />
<meta property="og:title" content="your_link_title" />
```

- Open the **Sharing Debugger** to verify that your server is returning the correct metadata to Facebook for sharing.
