Notes

Filtering app_id and skan_conversion_id using the filtering field is currently not supported.

The dma breakdown is not available for the estimated_ad_recall_rate metric or video_thruplay_watched_actions metric.

The dma breakdown employs a sampling methodology to compute unique metrics like reach. In instances where there are a large number of DMA regions with comparatively low volumes, they might not be represented in the sample or could be scaled up to a power of 2. Therefore, it’s advisable to query the corresponding impressions as well for enhanced accuracy.

frequency_value is used with reach only. For example, how frequently a unique user saw an ad.

By design, image_asset and video_asset breakdowns are not available at the ad account level for assets used in Dynamic Creative.

Ad actions video_p25_watched_actions, video_p50_watched_actions, video_p75_watched_actions, video_p95_watched_actions, and video_p100_watched_actions do not support region breakdown.

All Dynamic Creative asset breakdowns only support a limited set of metrics:

Dynamic Creative Breakdowns	Supported metrics for Dynamic Creative Breakdowns
`ad_format_asset` `body_asset` `call_to_action_asset` `description_asset` `image_asset` `link_url_asset` `title_asset` `video_asset`	`impressions` `clicks` `spend` `reach` `actions` `action_values`

Hourly breakdowns

Hourly stats are now an available breakdown using the following breakdowns:

hourly_stats_aggregated_by_advertiser_time_zone

hourly_stats_aggregated_by_audience_time_zone

See Combining Breakdowns for limits on number of breakdowns you may request with the hourly breakdown. Hourly breakdowns do not support unique fields, which are any fields prepended with unique_*, reach or frequency. reach and frequency fields will return 0 when hourly breakdowns are in use.

Action breakdown

Group results in the actions field. You can use the following breakdowns for action_breakdowns:

The following are the possible breakdowns that can be supplied into the action_breakdowns field.

action_device
conversion_destination
matched_persona_id
matched_persona_name
signal_source_bucket
standard_event_content_type
action_canvas_component_name
action_carousel_card_id
action_carousel_card_name
action_destination
action_reaction
action_target_id
action_type
action_video_sound
action_video_type
is_business_ai_assisted

If action_breakdowns parameter is not specified, action_type is implicitly added as the action_breakdowns.

Total count in `actions`

The total count (sum) of all values returned in group results (actions).

This result may not equal total_actions since fields returned in actions are hierarchical and include detailed actions not counted.

total_actions - 33
    page_engagement - 10
        post_engagement - 10
            link_click - 2
            comment - 3
            post_reaction - 3
            like - 2
    mobile_app_install - 12
    app_custom_event - 11
        app_custom_event.fb_mobile_activate_app - 6
        app_custom_event.other - 5

In this example, post_engagement is a sum of link_click, comment, like, and post_reaction, where post_reaction is the count of all reactions, including likes. The total_actions field represents a sum of top-level actions for an object, such as page_engagement, mobile_app_install, and app_custom_event.

Combining breakdowns

Due to storage constraints, only some permutations of breakdowns are available. Permutations marked with an asterisk (*) can be joined with action_type, action_target_id and action_destination which is the name for action_target_id.
