I am using Twitter Ads API to retrieve campaign statistics and there is a difference between the impressions the API returns and the one shown in the Ads dashboard.
I am passing the start_date and end_date converted to UTC in Ads account timezone with ISO 8601 format. When I compare promoted_tweet_timeline_impressions with the Impressions metric in the dashboard, the difference is there, other metrics matches though.
Can someone please help me with this? How the impressions in the dashboard gets calculated?
