We are trying to report on Lead Derrived Metrics (specifically number of leads, lead rate and cost per lead) using the Ads API (https://dev.twitter.com/ads/analytics/metrics-derived). In the Metrics and Segmentation documentation, it says promotion_card_responses, promoted_tweet_search_card_engagements and promoted_tweet_timeline_card_engagements is Deprecated, and I found this notification on the support forums: Announcement: Deprecation of Card Analytics
We need to tell our users how well a specific promoted Tweet performed from a lead generation perspective, and don’t know which metrics to use. We thought that perhaps the conversion metrics would be of use to us but we can’t find any confirmation of this. Please assist?
