Background

According to iOS 14 new privacy policy, most carriers need to follow Apple's ATT (App Tracking Transparency) to get users' approve before tracking IDFA. If users don't allow tracking, then we need to use SKAdNetwork to do attribution tracking instead.

In order to enable customers to use the third-party monitoring, FuseClick also support tracking with AppsFlyer, Adjust, Branch, Kochava and other 3rd-party companies to ensure the consistency of customer data;

General SKAdNetwork Set up

  • Create SKAdNetwork

Firstly, you need to register with Apple Developer. After registration, you will be able to obtain your ad network ID from Apple. In order to verify the verification process of APP install, channel developers need to put the ad network ID in their app's information property list.
Secondly, the private key and public key need to be generated. On the ad network server, this set of keys will be used to generate the signature; Next, please use the signature to set the value of the <SK Store Product Parameter AdNetwork Attribution Signature" parameter.

5. Data postback verification process

FuseClick received postback and checked for required parameters: ad network ID, Apple App ID (consistent with app ID in offer detail), campaign ID. In order to verify that the request is from apple, the signature must be verified. Apple's public key is used to decode the signature and compare the decoded information with the byte array reconstructed with the same parameters. A UTF-8 string is created by placing the parameters in a fixed order and separated by the implicit character '\u2063'.
 
 
You will see all the parameters that SKAdNetwork sends to you:
 
{
"version" : "2.2",
"ad-network-id" : "com.example",
"campaign-id" : 42,
"transaction-id" :"6aafb7a5-0170-41b5-bbe4-fe71dedf1e28",

"redownload": true,
