EAC recommendations

Revenue events (all ad networks)

For any event that represents revenue, we recommend sending:

• revenue or price (number)
• currency (string, e.g. EUR, USD)

Meta matching (send once per installation, as early as possible)

To improve matching quality on Meta, send events including the following parameters if you can fullfill them:

• email
• name (first + last name in the same field)
• phone_number
• date_of_birth (recommended format: YYYY-MM-DD)

What If You Don't Install the SDK?

tip

If you are only interested in iOS attribution and running only Tiktok, Google or Meta (no Apple Ads), you might be able to get away without installing the Appstack SDK.

See the SDK-less attribution documentation for more details.
