iOS 14+ & SKAdNetwork Support

Introduction

Due to the IDFA changes Apple is implementing on its iOS 14 release, BidMachine is adding support to Apple's SKAdNetwork attribution to allow our programmatic demand buyers to track installs and conversions on iOS 14 and future versions. Besides adding support for Apple's SKAdNetwork, BidMachine will also support additional data for contextual advertising to help our partners boost their targeting and modeling when IDFA is not present.

The diagram below gives an overview of how the integration on an app/publisher level will work and how the information will flow during the auction on bid requests and responses.

SKAdnetwork IDs

Partners who would like to have their SKAdNetwork ID added to the publisher's info.plist and use BidMachine's SKAdNetwork solution should share their ID with their account manager. If you don't have one yet, you can register with Apple here.
BidMachine will provide publishers an integration guide that includes all SKAdNetwork IDs that should be added into their plist.

Here is the current list of all SKAdNetwork IDs that are part of the guide:

Bid Request

All additional fields that BidMachine will pass in its BidRequests on iOS 14+ versions are described below and divided into categories, SKAdNetwork data, Device IDs, Contextual Data, and Additional Contextual Data.

SKAdNetwork request data

Object Attribute Description Type Example
BidRequest.imp.ext.skadn version

The version of SKAdNetwork SDK. Should be "2.0" or higher. 

Note: With the release of SKAdNetwork 2.1, this field is deprecated in favor of the BidRequest.imp.ext.skadn.versions to support an array of version numbers.

String "version":"2.0"
BidRequest.imp.ext.skadn versions Array of strings containing the supported skadnetwork versions. Always "2.0" or higher. array of string "versions": ["2.0", "2.1", "2.2"]
BidRequest.imp.ext.skadn sourceapp ID of publisher app in Apple’s App Store. Should match `BidRequest.app.bundle` String "sourceapp":"1232526187"
BidRequest.imp.ext.skadn skadnetids A subset of SKAdNetworkItem entries in the publisher app’s info.plist that are relevant to the DSP. String Array

[

  "87YHBND3GG.skadnetwork",

  "DBNK45HIER.skadnetwork"

]

Example:

{
  "imp": [
    {
      "ext": {
        "skadn": {
          "version": "2.0",
          "versions": ["2.0", "2.1", "2.2"],
          "sourceapp": "880047117",
          "skadnetids": [
            "cdkw7geqsh.skadnetwork",
            "qyjfv329m4.skadnetwork"
          ]
        }
      }
    }
  ]
}

BidResponse

SKAdNetwork response data

If the bid request to the DSP included the BidRequest.imp.ext.skadn object, the DSP should respond by adding the BidResponse.seatbid.bid.ext.skadn object into their bid response. If the object is present in the response, then BidMachine is able to submit the click data and signature to the productView for attribution.

These are the properties of the BidResponse.seatbid.bid.ext.skadn object:

Attribute Description Type Example
version The version of SKAdNetwork SDK. Should be "2.0" or higher.  String "version":"2.0"
network

A SKAdNetwork id should match one of the items in the skadnetids array in the request

String "network":"87YHBND3GG.skadnetwork"
campaign Campaign ID compatible with Apple’s spec. As of 2.0, should be an integer between 1 and 100, expressed as a string String "campaign":"1"
itunesitem ID of advertiser’s app in Apple’s app store. Should match BidResponse.bid.bundle String "itunesitem":"1232526187"
fidelities Supports multiple fidelity types introduced in SKAdNetwork v2.2 object array "fidelities": [ { "fidelity": 0, "signature": "MEQCIEQlmZRNfYzK…", "nonce": "473b1a16…", "timestamp": "1603246928149" } ]
nonce

An id unique to each ad response

Note: With the release of SKAdNetwork v2.2, this field is deprecated in favor of the BidResponse.seatbid.bid.ext.skadn.fidelities.nonce to support multiple fidelity-types.

String "nonce":"a9ff03c2-d7ef-11ea-87d0-0242ac130003"
sourceapp ID of publisher’s app in Apple’s app store. Should match BidRequest.imp.ext.skad.sourceapp String "sourceapp":"123456789"
timestamp

Unix time in millis string used at the time of signature

Note: With the release of SKAdNetwork 2.2, this field is deprecated in favor of the BidResponse.seatbid.bid.ext.skadn.fidelities.timestamp to support multiple fidelity-types.

String "timestamp": "1596723499"
signature

SKAdNetwork signature as specified by Apple.

Note: With the release of SKAdNetwork 2.2, this field is deprecated in favor of the BidResponse.seatbid.bid.ext.skadn.fidelities.signature to support multiple fidelity-types.

String "signature": "MZHKJHKhKJH…"

BidResponse.seatbid.bid.ext.skadn.fidelities object:

Attribute Description Type Example
fidelity The fidelity-type of the attribution to track Integer "fidelity": 0
nonce

An id unique to each ad response.

String "nonce": "473b1a16-b4ef-43ad-9591-fcf3aefa82a7
timestamp Unix time in millis string used at the time of signature String "timestamp": "1594406341"
signature SKAdNetwork signature as specified by Apple String "signature": "MEQCIEQlmZRNfYzK…"

Click Through & Click Tracking behavior

If SKAdNetwork is enabled and the bid response contains valid skadn object:

  • iOS SDK will open SKStoreProductViewController with the skadn values
  • VAST ClickThrough, CompanionClickThrough & MRAID.open(), or standard HTML a href= links will be processed by SDK immediately in the background. HTTP redirects will be processed but any response that is not a 3xx HTTP redirect will be ignored.
  • VAST ClickTracking and CompanionClickTracking will continue to work the same way.

If there is no skadn in the bid response, the SDK will fallback to the behaviour of following the click through to its destination.
