Setting Conversion Window/Ads Action Stats via Facebook Ads Api

Question

I have a requirement to add 'Conversion Window' (as above) to an existing Java application which creates batches of Facebook ads. I can't find how to set Conversion Window via the API or how to get a list of them from the API.

This is the most relevant information I've found:

https://developers.facebook.com/docs/marketing-api/reference/ads-action-stats

But it doesn't give me all of what I need.

Answer 1

Although named similarly, those are two different things.

Conversion window specified with bidding is a time period used for optimization of ad delivery. The parameter is called attribution_specand can be set on adset. Valid combinations are described here.

Adset with conversion window of 1-day view, 7-day click would be specified like this:

{
   "name": "Adset name",
   "attribution_spec": [
      {
         "event_type": "VIEW_THROUGH",
         "window_days": 1
      },
      {
         "event_type": "CLICK_THROUGH",
         "window_days": 7
      }
   ],
   ... other adset params ...
}

Attribution window is a parameter used when loading insights. Using that you can get the stats broken down into different time periods, which can be handy for advanced analytics.
