The Analytics API exposes campaign performance statistics using the same organization API key authentication as the Campaigns API. OpenAPI version 1.1.0 adds date-scoped campaign trends, sequence-email performance, organization rollups, lead-level outcomes, and lead activity while keeping the lifetime campaign summary endpoint intact.
Use GET /api/v1/campaigns/{campaign_id}/analytics for the existing no-date-filter campaign summary.
Query /analytics/timeseries?filter[start_date]=2026-05-01&filter[end_date]=2026-05-31&granularity=week.
Read account-level totals with GET /api/v1/analytics/overview?filter[start_date]=2026-05-01&filter[end_date]=2026-05-31.
Use /analytics/sequence?filter[start_date]=2026-05-01&filter[end_date]=2026-05-31&granularity=week and lifetime /analytics/leads.
The API exposes human reply metrics and end-autoreply metrics separately.
reply_rate and not end_autoreply_rate.leads_contacted - all_bounces.
