# Ad Impression-Level Revenue Connections

- [AppLovin Max User Revenue API](https://docs.adlibertas.com/data-integrations/ad-impression-level-revenue-connections/applovin-max-user-revenue-api.md)
- [ironSource Ad Revenue Measurement Integration](https://docs.adlibertas.com/data-integrations/ad-impression-level-revenue-connections/ironsource-ad-revenue-measurement-integration.md): IronSource makes it easy to collect impression-level data. While they do provide a post-back app event, it’s much easier for AdLibertas to collect the impression-level data from the ironSource API.
- [Impression level tracking with Admob Mediation](https://docs.adlibertas.com/data-integrations/ad-impression-level-revenue-connections/impression-level-tracking-with-admob-mediation.md)
- [Collecting MoPub Impression-Level Data as a Firebase Event](https://docs.adlibertas.com/data-integrations/ad-impression-level-revenue-connections/collecting-mopub-impression-level-data-as-a-firebase-event.md): Today MoPub doesn’t offer an API providing impression-level events. The information is only allowed as a post-back to the app.
