Get LinkedIn org analytics

Returns aggregate analytics for a LinkedIn organization page. Parallel to /v1/accounts/{id}/linkedin-aggregate-analytics (which handles personal accounts only). Backed by LinkedIn's organizationalEntityShareStatistics, organizationalEntityFollowerStatistics, and organizationPageStatistics endpoints. Response shape matches /v1/analytics/instagram/account-insights. Max 89 days, defaults to last 30 days. Requires the Analytics add-on. Scope requirements: r_organization_social, r_organization_followers, and r_organization_admin must all be present on the account. Accounts connected before these scopes were included in the OAuth flow will return 412 with a reauth hint. Enforced by this endpoint: - Page-view metrics accept only metricType=total_value (LinkedIn omits per-day segmentation even when the API is called with DAY granularity, so a time-series response would be meaningless). - Date range capped at 89 days. LinkedIn-side platform limits (not re-enforced here, but worth knowing for larger ranges in a future release): - Follower stats: rolling 12-month window, end must be no later than 2 days ago. - Share stats: rolling 12-month window.

Get LinkedIn post reactions

Returns individual reactions for a specific LinkedIn post, including reactor profiles (name, headline/job title, profile picture, profile URL, reaction type). Only works for organization/company page accounts. LinkedIn restricts reaction data for personal profiles (r_member_social_feed is a closed permission).
