SKAdNetwork 개인정보 보호 임계값은 무엇입니까?

SKAdNetwork 2.2 (iOS 14.5에서 사용 가능) 의 포스트백은 다음과 같습니다.

{
  "version" : "2.2",
  "ad-network-id" : "com.example",
  "campaign-id" : 42,
  "transaction-id" : "6aafb7a5-0170-41b5-bbe4-fe71dedf1e28",
  "app-id" : 525463029,
  "attribution-signature" : "MEYCIQDTuQ1Z4Tpy9D3aEKbxLl5J5iKiTumcqZikuY/AOD2U7QIhAJAaiAv89AoquHXJffcieEQXdWHpcV8ZgbKN0EwV9/sY",
  "redownload": true,
  "source-app-id": 1234567891,
  "fidelity-type": 1,
  "conversion-value": 20
}

See this Apple documentation page for more details.

Of these parameters, conversion-value and source-app-id will only be included when they meet a secret Apple 'privacy threshold'. This is in order to protect user privacy. Apple has not released any details about what this threshold is, and many ad networks are currently (as of February, 2021) reporting that very few postbacks include them.

In Branch's own reporting, activity that hasn't met the minimum privacy threshold will show these values as "Unpopulated"; activity that has met this threshold will include the appropriate value.
