Konduit Accelerate Module

The Konduit Accelerate module applies the Konduit video acceleration optimization to a publisher’s existing Prebid setup. This optimization provides publishers with tools to monetize previously lost revenue and drive higher fill rates on their video inventory.

To install the module, follow these instructions:

Step 1: Prepare the base Prebid file

Build your Prebid.js package in one of two ways:

  • Receive an email package from the Prebid Download page.

  • From the command line, run
    gulp build --modules=konduitWrapper,...

Step 2: Implement module code on page

  • Add konduitId as config using setConfig prebid method (pbjs.setConfig({ konduit: { konduitId: your_konduit_id } }))

  • Insert the Konduit module code in the source code of your page.
    The module exposes the pbjs.adServers.konduit.processBids function.

  • Provide input parameters to the function. (All parameters are shown in the following table.)

Param Type Description Default
bid object Prebid object with VAST URL that should be cached If the bid parameter is not passed then first winning bid will be used
bids array An array of Prebid objects with VAST URL that should be cached If the bids parameter is not passed then all received bids will be used
adUnitCode string adUnitCode where a winner bid can be found -
timeout number Max time to wait for Konduit response with cache key and kCpm data 1000
callback function The callback function is called once Konduit caches data for the bid. Arguments of this function are error and bids (error should be null if Konduit request is successful). -

Konduit Accelerate module respects the Prebid enableSendAllBids flag and supports both ‘Send All Bids’ and ‘Use only the winning bid’ scenarios.

Prebid set the enableSendAllBids flag to true by default and it can be explicitly disabled in Prebid config if needed.

  enableSendAllBids: false

Please refer to Publisher API Reference (Send All Bids) for more information on the Send All Bids settings.

Step 3: Configure Google Ad Manager (GAM)

In order for Konduit’s module to be completely integrated, line item creatives need to be adjusted in GAM. Please contact support@konduit.me for assistance.

In most cases it will be enough to update a creative VAST URL in related GAM line items.

Konduit platform supports the ‘Send all bids’ scenario, but the GAM configuration can differ slightly depending on whether or not this feature is enabled.

  • If Send all bids is disabled (a single winning bid is used), update the GAM line item creative URL as follows: https://p.konduit.me/api/vastProxy?konduit_hb=1&konduit_hb_awarded=1&konduit_cache_key=%%PATTERN:k_cache_key%%&konduit_id=%%PATTERN:k_id%%

  • If Send all bids is enabled, update the GAM line item creative URL as shown here: https://p.konduit.me/api/vastProxy?konduit_hb=1&konduit_hb_awarded=1&konduit_cache_key=%%PATTERN:k_cache_key_BIDDERCODE%%&konduit_id=%%PATTERN:k_id%%

k_cache_key_BIDDERCODE is a bidder-specific macro. Replace ‘BIDDERCODE’ with an actual bidder code, such as k_cache_key_appnexus.

Note that the creative URL contains a few custom macros that allow Konduit platform to combine different data for predictive insights functionality.

Macro name Example Comment
k_id %%PATTERN:k_id%% The macro passes Konduit client id provided in a publisher call back to Konduit platform. Should be used as is.
konduit_id %%PATTERN:konduit_id%% This macro is deprecated and k_id should be used instead
k_cache_key %%PATTERN:k_cache_key%% The macro is passing a cache key so that Konduit platform is able to fetch current bid tag for processing. This macro is recommended for use in a ‘single bid’ mode. In ‘send all bids’ mode it always represents a winning bid.
konduit_cache_key %%PATTERN:konduit_cache_key%% This macro is deprecated and k_cache_key should be used instead
k_cache_key_BIDDERCODE %%PATTERN:k_cache_key_rubicon%% The macro is passing a cache key so that Konduit platform is able to fetch a bidder tag for processing. This macro should be used in a ‘send all bids’ mode.

Sample Code

We recommended using the Konduit module function call in the bidsBackHandler callback function.

pbjs.que.push(function() {
    konduit: {
      konduitId: your_konduit_id,
    bidsBackHandler: function(bids) {
      var winnerBid = pbjs.getHighestCpmBids('videoAd')[0];

        bid: winnerBid,
        adUnitCode: videoAdUnit[0].code,
        timeout: 1500,
        callback: function (error, bids) {
          var videoUrl = pbjs.adServers.dfp.buildVideoUrl({
