## Code Examples

##### Web SDK

```js
if (HLS) {
  let drmConfiguration = {
    integration: 'keyos',
    customdata: '<CUSTOMDATA>',
    fairplay: {
      licenseAcquisitionURL: '<LICENSE_KEY_URL_FAIRPLAY>',
      certificateURL: 'CERTIFICATE_URL>',
    },
  };
  player.source = {
    sources: {
      src: '<HLS_STREAM_URL>',
      type: 'application/x-mpegurl',
      contentProtection: drmConfiguration,
    },
  };
} else if (DASH) {
  let drmConfiguration = {
    integration: 'keyos',
    customdata: '<CUSTOMDATA>',
    playready: {
      licenseAcquisitionURL: '<LICENSE_KEY_URL_PLAYREADY>',
    },
    widevine: {
      licenseAcquisitionURL: '<LICENSE_KEY_URL_WIDEVINE>',
    },
  };
  player.source = {
    sources: {
      src: '<DASH_STREAM_URL>',
      type: 'application/dash+xml',
      contentProtection: drmConfiguration,
    },
  };
}
```

##### Android SDK

```java
DRMConfiguration drmConfiguration = KeyOSDRMConfiguration.Builder
    .keyOsDrm()
    .widevine(
        new KeyOSKeySystemConfiguration("<CUSTOM_DATA>", "<LICENSE_KEY_URL_WIDEVINE>")
    )
    .build();
TypedSource typedSource = new TypedSource.Builder()
    .src("<DASH_STREAM_URL>")
    .drm(drmConfiguration)
    .build();
SourceDescription sourceDescription = SourceDescription.Builder.sourceDescription()
    .sources(typedSource)
    .build();
theoplayer.getPlayer().setSource(sourceDescription);
```

##### Legacy iOS/tvOS SDK (4.12.x)

```swift
public static var buyDRMkeyOS: SourceDescription {
    let licenseAcquisitionURL: String = "<LICENSE_KEY_URL_FAIRPLAY>"
    let certificateURL: String = "<CERTIFICATE_URL_FAIRPLAY>"
    let token: String = "<TOKEN_FAIRPLAY>"
    let type: String = "application/x-mpegURL"
    let src = "<HLS_STREAM_URL>"
    let drm: KeyOSDRMConfiguration = KeyOSDRMConfiguration(licenseAcquisitionURL: licenseAcquisitionURL, certificateURL: certificateURL, customdata: token)
    let typedSource: TypedSource = TypedSource(src: src, type: type, drm: drm)
    let source: SourceDescription = SourceDescription(source: typedSource)
    return source
}
```
