iOS 14 Support
Overview
This guide represents our current proposed changes to Unity Ads auction logic for our programmatic partners. We encourage you to revisit this documentation periodically to ensure that you have the most up-to-date guidance.
Note: All fields and names are case-sensitive.
Bid Request Change
BidRequest.imp.ext.skadn
If a DSP has at least one SKAdNetworkItem in the publisher app’s Info.plist, Unity will include this object in the bid request. This provides the information required to create a signature.
| Field | Type | Description | Example |
|---|---|---|---|
version |
string | Version of skadnetwork supported, which is always 1.0, 2.0, or higher. Depends on both the OS version and the SDK version. |
"version":"2.0" |
sourceapp |
string | Publisher app ID in Apple’s App Store. Should match app.bundle value in the bid request. | "sourceapp":"123456789" |
skadnetids |
string array | A lowercase list of DSP-specific SKAdNetworkItem entries that appear in the publisher app’s Info.plist_ file. |
"skadnetids": ["dsp1.skadnetwork"] |
BidRequest.device.ext.atts
Unity will include the status for app tracking authorization in the BidRequest.device.ext.atts field. For more information about this field, please refer to Apple’s API documentation.
| Field | Type | Description | Example |
|---|---|---|---|
atts |
integer | The status value for app tracking authorization. Possible values are:
|
"atts":2 |
Bid Response Change
BidResponse.seatbid.bid.ext.skadn
If a bid request includes a BidRequest.imp.ext.skadn, a DSP can send a BidResponse.seatbid.bid.ext.skadn object in response. If present, Unity will use the signature of this object for attribution. For more information, please refer to Apple’s API documentation.
| Field | Type | Description | Example |
|---|---|---|---|
signature |
string | SKAdNetwork signature specified by Apple. | "signature": "WOBQQIRTnAcfYzF..." |
network |
string | Ad network identifier used in signature. Should match one of the items in the skadnetids array in the request. |
"network":"5HUO92BLLQ.skadnetwork" |
version |
string | Version of desired SKAdNetwork. | "version":"2.0" |
campaign |
string | Campaign ID compatible with Apple’s spec. As of version 2.0, should be an integer between 1 and 100, expressed as a string. |
"campaign":"83" |
itunesitem |
string | Advertiser app ID in Apple’s App Store. Should match bid.bundle in the bid response. | "itunesitem":"987654321" |
nonce |
string | An id that is unique to each ad response. | "nonce":"385c9n44-a9ik-28fd-8247-gjk2efoa56a9" |
sourceapp |
string | ID of publisher app in Apple’s App Store. Should match imp.ext.skadn.sourceapp in the bid request. |
"sourceapp":"123456789" |
timestamp |
string | Unix time in milliseconds at the time the signature was generated. | "timestamp": "1225091839" |
Device IDs
Note: Unity will pass IDFA where present. Where IDFA is not present, IDFV will be passed.
| Name | Object | Type | Description | Example |
|---|---|---|---|---|
IDFA |
Device.ifa |
string | Preferred device advertising identifier. It has a value of 00000000-0000-0000-0000-000000000000 when permission to track has not been granted. |
ABC123AB-1234-5678-A1B2-123ABCBCD789 |
