This adapter is known to use an HTTP 1 endpoint. Header bidding often generates multiple requests to the same host and bidders are encouraged to change to HTTP 2 or above to help improve publisher page performance via multiplexing.


Kargo is an invitation-only marketplace. Please reach out to your Kargo account manager to get setup. Also, you must test on a mobile device, or emulate a mobile device by manipulating the user agent string sent to the server.

Bidder Settings

The Kargo bid adapter uses browser local storage. Since Prebid.js 7.x, the access to it must be explicitly set.

pbjs.bidderSettings = {
  kargo: {
    storageAllowed: true

Bid Params

Name Scope Description Example Type
placementId required The placementId of the ad slot. '_jWuc8Hks' string

ORTB Blocking

Kargo supports blocking advertisers in badv and categories in bcat parameters. The blocked advertisers/categories list has no length limitation, but response timeout is more likely to occur as the number of entries grow. Blocked advertisers list (badv) is an array of domains as strings. Blocked categories list (bcat) is an array of IAB categories as strings.

For example:

Globally defined ORTB Blocking

  ortb2: {
    badv: ["", ""],
    bcat: ["IAB23-1", "IAB23-5", "IAB25-3", "IAB25-2"]

ORTB Blocking specific only to the Kargo bidder

  bidders: ['kargo'],
    ortb2: {
      badv: ["", ""],
      bcat: ["IAB23-1", "IAB23-5", "IAB25-3", "IAB25-2"]
