To integrate Amplify Video managed resources into your application, use the Amplify API javascript library and import the queries generated by Amplify.

```javascript
import Amplify, { API, graphqlOperation } from 'aws-amplify';
import * as queries from '../../graphql/queries';
```

Use the listVodAssets query to retrieve all assets in the CMS.

```javascript
const assets = await API.graphql(graphqlOperation(queries.listVodAssets));
```

You can also use GraphQL subscriptions to monitor for any newly created assets.

```javascript
API.graphql(
  graphqlOperation(onCreateVodAsset),
).subscribe({
  next: (((data) => {
    const { items } = this.state;
    items.push(data.value.data.onCreateVodAsset);
    this.setState({
      items,
    });
  })),
});
```

If you're using content protection, you may want to omit calling the token field within the CMS, as it will incur extra costs calling the lambda resolver for tokens each time you call ListVodAssets. You can edit the queries within  `/src/graphql/queries.js`

```javascript
export const listVodAssets = /* GraphQL */ 
  query ListVodAssets(
    $filter: ModelvodAssetFilterInput
    $limit: Int
    $nextToken: String
  ) {
    listVodAssets(filter: $filter, limit: $limit, nextToken: $nextToken) {
      items {
          ...
        video {
          id
          token // remove this if you don't want lambda to be called on each invocation
        }
```
