Beta

The External API is in beta. Endpoints, parameters, and response shapes may change — including breaking changes — in future releases. Pin to documented behavior before relying on it in production.

Filter to a single broadcast type.

includeArchived?string

When true, also include archived (non-visible) messages.

limit?integer

Max messages to return.

Get per-day campaign insights

Per-day insights time series for one marketing message campaign, over an optional `startDate` / `endDate` window. Daily insights are only available for campaigns created on or after 2026-03-01; older campaigns return `400`, as does an org not connected to Meta Ads.

Get (a single) marketing message metadata

One marketing message's metadata (no insight numbers). For the per-send delivery funnel, call `GET /marketing-messages/{broadcastId}/insights`.
