 Finally, the server-side component will look for the following `properties` and handle them specially:
 
-- `ip` (this should be the `ip` of your customer--this is not collected by Segment's libraries out-of-the-box)
+- `ip` (this should be the `ip` of your customer--this is not collected by Segment's libraries out-of-the-box. Pass this into the payload under context so that AppsFlyer can properly attribute it.)
 - `timestamp` (refer to AppsFlyer's docs on [how they process timestamps](https://support.appsflyer.com/hc/en-us/articles/207034486-Server-to-Server-In-App-Events-API-HTTP-API-){:target="blank"}. Since the libraries generate a [timestamp](/docs/connections/spec/common/#timestamps), Segment always sets this value)
 - `currency` (defaults to `"USD"`)
 - `revenue` (For `Order Completed` events, precedence is given to `total`, falling back to `properties.revenue`)
