Prebid Integration

The Rumble player can support Prebid thanks to two sets of functionalities in the player:

  1. api.clearAds() / api.insertAd( [timecode] , [waterfall] ) This allows you to setup what ad stacks you want to run, in a simple set up you can use these to set up the ads within the player when the bidding is completed.

  2. api.on(‘adRequest’, function( [ad] ) { … } ); This allows you to intercept an ad request before it is called, where you can replace the tag with a new one. You can also ask the player to wait if the bidding has not completed yet.

Simple pre-roll Setup

The following is an example of implementing a pre-roll ad with Prebid.

This example uses a test version of Prebid.js and is not recommended for production use. You should build Prebid from source or use their Download page to make sure only the necessary bidder adapters are included.

Also make sure to replace [PUBID] with your publisher ID, this can be found in any of the embed codes you are provided on Rumble.com while being logged into your account.

  /* Prebid code */
  var pbjs = pbjs || {};
  pbjs.que = pbjs.que || [];

  /*
   Prebid Video adUnit
   */

  var videoAdUnit = {
    code: 'video1',
    sizes: [640,480],
    mediaTypes: {
      video: {
        context: "instream"
      }
    },
    bids: [
      {
        bidder: 'appnexus',
        params: {
          placementId: '13232361', // Add your own placement id here

          video: {
            skipppable: true,
            playback_method: ['auto_play_sound_off']
          }
        }
      }
    ]
  };

pbjs.que.push(function(){
    pbjs.addAdUnits(videoAdUnit); // add your ad units to the bid request

    pbjs.setConfig({
      debug: true,
      cache: {
        url: 'https://prebid.adnxs.com/pbc/v1/cache'
      }
    });

    pbjs.requestBids({
      bidsBackHandler: function(bids) {
        var videoUrl = pbjs.adServers.dfp.buildVideoUrl({
          adUnit: videoAdUnit,
          params: {
            iu: '/19968336/prebid_cache_video_adunit',
            cust_params: {
              section: "blog",
              anotherKey: "anotherValue"

          }
        });

        setRumblePlayerAd( videoUrl );
      }
    });
  });
</script>

The above code can easily be modified to support more ads, and use mid or post rolls.

More robust example (advanced)

The following example shows a more advanced Prebid integration strategy. This example does not include the Prebid code as it is dependent on when you want to do the bidding.
