Please can you tell me how to get 7d_view and 28d_click conversion information out of the Facebook marketing API, I only really need the count and amount of sales but I'm struggling to find the values in the response when I do the following in PHP:
$campaign = new Campaign('[CAMPAIGN ID]');
$params = array('date_preset' => InsightsPresets::YESTERDAY, 'action_attribution_windows' => array('7d_view', '28d_click'));
$fields = array('campaign_id', 'campaign_name', 'reach', 'spend','social_spend', 'total_actions', 'total_unique_actions');
$insights = $campaign->getInsights($fields, $params);
foreach ($insights as $ins) {
var_dump($ins);
}
It executes and returns basic values e.g. Campaign name etc, but it does not seem to include any kind of conversion data.
I suspect I need to add something to the fields array - but I don't know what.
Sorry to ask, but the facebook documentation for the current version of the marketing API (v2.7) says the conversion attribution is deprecated but I can't find what it has been replaced with.
