  • Hey everyone, Im trying to integrate AppsFlyer with RevenueCat, but I cannot seem to hook things up properly. I get the AppsFlyer data on my customers but the event is never sent, there is neither successful nor unsuccessful events. Any pointers what i need to check? This is sandbox testing, do i need to add different keys and or apps for this, or do I use the same app IDs and dev key?

Hey ​@niko, the most common reason for AppsFlyer events not being dispatched is missing customer attributes. 

Our RevenueCat AppsFlyer Integration guide specifies which attributes are required for this integration:

 

2. Send device data to RevenueCat

The Appsflyer integration requires some device-specific data. RevenueCat will only send events into Appsflyer when the required Customer Attributes below are set for the device. Recommended attributes improve attribution matching quality.

Key Description Required
$appsflyerId Appsflyer Id. The unique Appsflyer identifier for the user ✅
$idfa iOS advertising identifier UUID ⚠️ (recommended)
$gpsAdId Google advertising identifier ⚠️ (recommended)
$idfv iOS vendor identifier UUID ⚠️ (recommended)
$amazonAdId Amazon advertising identifier ⚠️ (recommended)
$ip The IP address of the device ⚠️ (recommended)

​@chris_perriam hey thanks for the reply, i forgot to update this post. The problem was I was testing with the revenuecat test store. When i changed to appstore and google play sandbox everything worked fine. Not sure if I saw this in the docs, but if not, might be useful to be added.

Thanks again!
