Deprecations & Changes

Ads Insights API – Unique metrics deprecation

We have deprecated a number of unique metrics from the Ads Insights API on Oct 30, 2024, after which the API’s unique_actions and cost_per_unique_action_type fields will no longer return several action_type breakdowns. Fields counting total actions, like actions and cost_per_action_type, are unaffected and will continue to support existing action_type breakdowns.

With these updates, we aim to improve the quality and consistency of metrics we are providing for Meta ads. For continued insight into customer conversions, please see our recent updates to Attribution Windows, including first conversion attribution, available via the Ads Insights API’s action_attribution_window parameter.
