The time window(s) used to attribute actions (such as link clicks or conversions) to ads. For example, 7d_click means attribute clicks up to 7 days after the ad was shown. In the Insights API, you can specify multiple windows (e.g. ["1d_click","28d_view"]). This affects metrics like conversions and actions because only events within those windows are counted.
action_attribution_windows=['28d_click','1d_view']
