# Custom API Integration

Custom API integration gives you full control over the data used in the video.\
It’s a flexible, secure option that allows you to power personalization using real-time data from your own servers.

* Enables fully custom logic and business rules
* Data is fetched directly from your backend and never exposed to Blings
* Supports advanced personalization while keeping the integration lightweight

#### Fetch Data via Custom Code

Use your own code to fetch data from an API, then pass it into the Blings player during initialization.

```js
fetch('https://my-api.example.com/user-data/123')
  .then(response => response.json())
  .then(userData => {
    BlingsPlayer.create({
      // project: {...},
      // settings: {...},
      data: userData
    });
  });
```
