Description of change

Supports calling bider adapter aliases with prebidServer adapter (OpenRTB endpoint only). In a prebid setup, add a known alias to the s2sConfig.bidders array, and that will take part in the s2s auction.

Example config - known alias

pbjs.setConfig({
  s2sConfig: {
    enabled: true,
    accountId: '123-456',
    endpoint: 'https://prebid.adnxs.com/pbs/v1/openrtb2/auction',
    bidders: ['appnexus', 'brealtime'],
  },
});

// brealtime and appnexusAst are both aliases of appnexus
// appnexus and brealtime will take part in the s2s auction since they are listed in s2sConfig.bidders
// appnexusAst will be run client-side
pbjs.addAdUnits({
    // ...
    bids: [
      {
        bidder: 'appnexus',
        params: { placementId: '123' }
      },
      {
        bidder: 'brealtime',
        params: { placementId: '123' }
      },
      {
        bidder: 'appnexusAst',
        params: { placementId: '456' }
      },
    ],
   // ...
  });

Example config - dynamic alias

pbjs.aliasBidder('appnexus', 'newAlias');

pbjs.setConfig({
  s2sConfig: {
    enabled: true,
    accountId: '123-456',
    endpoint: 'https://prebid.adnxs.com/pbs/v1/openrtb2/auction',
    bidders: ['newAlias'],
  },
});

// newAlias will take part in s2s auction
pbjs.addAdUnits({
    // ...
    bids: [
      {
        bidder: 'newAlias',
        params: { placementId: '123' }
      },
    ],
   // ...
  });

Is there a way to implement these aliases without tying prebidServerBidAdapter to the appnexusBidAdapter?

[matthewlane]

@bretg Yes, the aliases array can be copied into this file. In that case whenever an appnexus alias is added, modified, or removed, both arrays will need to be edited

Please update to be compatible with pbjs.aliasBidder thanks.

Any ETA to when this feature might be available ?
