Hi.
We've set up the RevenueCat + Appsflyer integration.
We built a Fire OS build and uploaded it to Live App Testing.
We're successfully processing payments and subscriptions, and we can see the data in RevenueCat.
We can also see that the data has been successfully sent to Appsflyer.
BUT we can't find this data in Appsflyer.
What are we doing wrong?

UPDATED!

Appsflyer replied that the problem lies in the request data between the servers (RevenueCat → Appsflyer).
I don't know how to fix this.

Hi there,

I’m Erik, happy to help!

I noticed you already received a response from support directly, and I can confirm that their recommendation aligns with what I would suggest as well.

To reiterate the previous response:

The app_id: app57b2627642 that AppsFlyer flagged is located in the custom_data field of the event body. This is a RevenueCat internal identifier and is not used by AppsFlyer for event routing. It’s simply metadata we attach for our own tracking.

The actual App ID used in our API call to AppsFlyer (in the URL path) matches your AppsFlyer dashboard. We’re sending events to:

https://api2.appsflyer.com/inappevent/(bundle_id) and receiving a 200 response, meaning AppsFlyer is successfully accepting the events.

I’d recommend going back to AppsFlyer support and sharing the following:

  • The app_id in custom_data is not the AppsFlyer app identifier, but internal metadata from RevenueCat

  • The correct app ID is being used in the API URL path

  • Events are returning a 200 response, so they are being received by AppsFlyer

At this point, AppsFlyer may need to investigate whether the events are being received but not attributed or displayed. Common reasons include processing delays or the AppsFlyer ID not matching a known device.

Let me know if you have any other questions!

Cheers,

Erik - Developer Support Engineer
