    }
  }],
  ...
}
```

### Ad Unit Setup for Multi-format: Banner, Video (Outstream)

```javascript
var adUnits = [
{
  code: '33across-hb-ad-123456-1', // ad slot HTML element ID
  mediaTypes: {
    banner: {
      sizes: [
          [300, 250],
          [728, 90]
      ]
    },
    video: {                                // We recommend setting the following video params
                                            // in Ad Unit rather than bidder params as per Prebid 4.0 recommendation.
      playerSize: [300, 250],               // required
      context: 'outstream',                 // required
      mimes: ['video/mp4','video/x-flv'],   // required
      protocols: [ 2, 3 ],                  // required, set at least 1 value in array
      plcmt: 2,                             // optional, defaults to 2 when context = outstream
      api: [ 1, 2 ],                        // optional
      skip: 0,                              // optional
      minduration: 5,                       // optional
      maxduration: 30,                      // optional
      playbackmethod: [1,3],                // optional
      battr: [ 13, 14 ],                    // optional
      linearity: 1,                         // optional
      minbitrate: 10,                       // optional
      maxbitrate: 10                        // optional
    }
  },
  bids: [{
    bidder: '33across',
    params: {
        zoneId: 'examplePub123',    // required
        productId: 'siab'           // required
    }
  }],
  ...
}
```

### App request config

Use `pbjs.setConfig()` or `pbjs.setBidderConfig()` for scenarios where prebid.js is in an App Webview.

``` javascript
pbjs.setConfig({
  ortb2: {
    app: {
      name: 'My APP'
    }
  }
});
```

### SRA Mode

We recommend using SRA mode to optimize the bidding process as this allows our adapter to group together bid requests for Ad Units pertaining to the same product and site ID thereby minimizing the number of http requests made to our endpoint. To enable SRA set the following bidder specific config under 33Across

```javascript
pbjs.setBidderConfig({
   bidders: ['33across'],
   config: {
      ttxSettings: {
        enableSRAMode: true
      }
   }
});
```
