# For Developers

Props Gratis automatically the token's metadata to your application / website URL via a URL parameter `metadata.`

The Metadata contains the data as defined by [OpenSea's metadata standard](https://docs.opensea.io/docs/metadata-standards#metadata-structure).

### Sample Repository

<https://github.com/Props-Labs/props-dynamic-token-example>

### Read Metadata

```javascript
const urlParams = new URLSearchParams(window.location.search);
const metadataParam = urlParams.get('metadata');

let metadata = null;

try {
    metadata = JSON.parse(metadataParam);
} catch(e) {
    console.error("Error parsing metadata", e);
}
```
