Custom Attribution Windows
To do custom attribution windows for Engagement data or ROAS, such as 3-Day or from "time of first app use", you can programmatically detect, in the app, if the timeframe is adequate before making the FB SDK call. For example, you could detect if <= 3 days had passed since first app use to decide whether to call a Purchase event. You could additionally call an alternate event after 3 days that is reserved only for this purpose.
Standard In-App Events
Use these standard events whenever possible, even if the actual event does not entirely correspond with the name. Doing so will give you out-of-the-box compatibility with Facebook and AdRules reporting systems, and allow bid management based on these events.
