iOS & SKAdNetwork

Justtrack supports the iOS 14 SKAdNetwork Integration starting from SDK version 2.4.2
Please make sure you are using this version.
The iOS attribution uses the IDFA - if available through ATT - and other attributes if unavailable for probabilistic attribution.
For attribution with iOS 14 and above, a signature is added to each ad click. Apple will be able to verify which ad the user is coming from upon the first app open of a user. A postback without user identification is sent back to the ad network for attribution.
Upon app launch, two methods have to be implemented. We already support these two methods in our justtrack SDK.
registerAppForAdNetworkAttribution(): This method is used to register the user for attribution
updateConversionValue(_:): This method is used to update the user’s conversion value. Updates will only be applied if the value is higher than the previous value.
For web traffic, as well as all cases where the IDFA is still available, the current attribution flow will apply. We attribute using the IDFA and anonymized fingerprinting and send back all relevant information via a postback.
Postbacks for installs and post install events can be provided by justtrack no matter if the IDFA is present or not. In the later case, without any user identifiers. Please refer to the for a detailed list.
If the IDFA is not present, the SKAdNetwork basic postback flow is the following:
The postback is sent to the attributed ad network by Apple after the timer expires.
The ad network forwards the postback to justtrack either through:
Enriching the postback with specific data (such as campaignID, campaign name, IP address, …) and forward it to justtrack
Most common: configuring a direct redirect of the postback to justtrack. On redirect, justtrack replies with the http status code to Apple.
justtrack enriches, validates and decodes the postback and sends it to the ad network.
justtrack sends one install postback, and several additional ones for in-app events based on the number of conversion value changes.\
Please forward the postbacks to this endpoint:
Endpoint
HTTP method
POST
Accepted content types
application/json
Return codes
200 OK, 400 Bad Request, 500 Internal Server Error
The body should contain a payload like:
When forwarding the postback to justtrack, please add the following parameters to the payload. By enriching the postback and adding the campaign information justtrack knows the exact campaign a user needs to be attributed to.
sourceCampaignId
Ad network internal campaign ID
sourceCampaignName
Ad network internal campaign name
pbReceivedAdNetworkDateTime
Time ad network received the SKAd postback in YYYY-MM-DD HH:MM:SS
When the SKAd postback is reveived by justtrack, it can be forwarded to the ad network including the following parameters.
{transaction-id}
A unique value for this validation; use to deduplicate install validation messages
{conversion-value}
{fidelity-type}
A value of 0 indicates a view-through ad presentation; a value of 1 indicates a StoreKit-rendered ad
{redownload}
true/false: indicates whether the user downloaded the app from the App Store again
{pbReceivedJustTrack}
Time justtrack received the postback from ad network
If no IDFA is present, a probabilistic attribution complying with Apple’s privacy guidelines is done.
An unsigned 6-bit value that the installed app provided by calling . Note: The conversion-value only appears in the postback if the installed app provides it, and if providing the parameter meets Apple’s privacy threshold
Please refer to the to see which parameters you can add.\
