appsflyer-sdkless-skadnetwork-client

iOS SDKLess + Sample App which demonstrates the usage of Appsflyer API - SKAdNetwork S2S get conversion value per user

The repository has 2 parts:

The AppsFlyerSDKLessSKAdNetworkClient - SDKLess code (Obj-C)
The Sample App (Obj-C + Swift)

SPEC

Call the SK API with GET request that has the following query params:

Key	Description
`uid`	appsflyer id
`app_id`	application id
`af_timestamp`	current time in miliseconds
`af_sig`	Create an HMAC SHA256 signature by concatenating the values of the timestamp, dev key, app id, and AppsFlyer id: `HmacSHA256(af_timestamp + DevKey + app_id + uid)`

app_id in a format - "idxxxxxxx" The HMAC is generated using SHA256 and uses the DevKey as the signature’s secret key. The account Dev Key is taken from the App Settings page in the AppsFlyer dashboard.

Example:

https://skadsdkless.appsflyer.com/api/v1.0/conversion-value?uid=LYPnL-sdJuSwjg-AQ2GTZehc&app_id=123456789&af_sig=b457aca5d23a6cbe512775578201&af_timestamp=1603034622

SK API will return the following conversion value response as JSON:

{
  "value": 43
}

Response codes

Code	Description
200	the conversion value
400	invalid request (params or headers missing or malformed)
401	invalid signature
404	uid not found/expired
503	server busy

API and Usage

  private let uid = "YOUR_APPSFLYER_ID"; //AppsFlyerLib.shared().getAppsFlyerUID()
  private let appId = "YOUR_APP_ID"; //ID - is a string with following format @"idXXXXXXXX"
  private let devKey = "YOUR_DEV_KEY";
    
  AFSDKLessClient.shared.requestConversionValue(withUID: self.uid, devKey: self.devKey, appID: self.appId) { (cv, error) in
     if let cv = cv?.intValue {
          // Tells to the Client to register For AdNetwork Attribution (iOS 11.3+)
          // Should be called only once
          AFSDKLessClient.shared.registerForAdNetworkAttribution()  
          
          // Tells to the Client to update conversion value 
          AFSDKLessClient.shared.updateConversionValue(cv)        
          task.setTaskCompleted(success: true)
      } else {
          task.setTaskCompleted(success: false)
      }
