In addition to the upcoming July 2018 deprecations we announced in February 2018, we will also deprecate
action_link_click_destination in July of 2018.
We will no longer support
action_carousel_card_name breakdowns for conversion metrics and for any calculated metrics in July of 2018. You can still get
unique_actions:link_click metrics grouped by these carousel card breakdowns and can still get conversion metrics without these carousel card breakdowns.
These are breaking changes which will impact all available versions of the API.
