}Fetch attribution metrics for a conversion destination GET
LinkedIn-only today. Returns conversion-attribution metrics (`externalWebsiteConversions`, `externalWebsitePostClickConversions`, `externalWebsitePostViewConversions`, `conversionValueInLocalCurrency`, `qualifiedLeads`, `costInLocalCurrency`) bucketed by date. Date-range constraints (passed through from LinkedIn): - `granularity=DAILY` is retained for ~6 months only - `granularity=ALL` with a range > 6 months auto-rounds to month boundaries - `granularity=MONTHLY`/`YEARLY` retains 24 months Throttle: LinkedIn caps adAnalytics at 45M metric values per 5-minute window across the calling token. Single-rule queries are well within that limit; surfaces as 429 if hit.
