SKAN Data Reporting
1. What is SKAdNetwork?
https://developer.apple.com/documentation/storekit/skadnetwork
2. SKAdNetwork Journey
1. When the media channel displays ads to users or users click on ads and jump to App Store, some parameters related to SKAdNetwork should be attached, such as target App package name, source App, ad offer ID, ad platform ID, etc.
2. When the target App is installed and launched, the target App needs to call Apple's new API (SE Method). Apple will then match the related parameters to learn which source App and media channel the user comes from, and then send postbacks to media channels.
Therefore, to guarantee SKAN running well, advertisers and media channels need to:
- Advertisers: Call Apple's new API to trigger SKAN attribution when conversion occurs.
- Media channels: Generate ad signature, call storekit to bring the signature, and receive Apple's postback.
3. Conversion Value
Conversion value represents the user's lifetime value, defined by Apple between 0 and 63. Please select numbers according to your needs. You can also refer to the following examples for guidance:
Super Simplified Version (optimize paid users):
Simplified Version (optimize payment amount):
Advanced Version (optimize mutiple events):
After defining the numbers, you can embed the code to call Apple's API and update the value when events are triggered.
4. How do media channels send the SKAdNetwork attribution results to SE?
1. POST
2. Send to the address:
