Preview a CRM or CDP account audience
Resolve a CRM-backed audience source (HubSpot list, Salesforce report/list view, Pipedrive person filter) or a CDP account group right now and return the recipient count plus a ≤25-row contact sample for the wizard preview card. Native Orbit audiences (segments, lists, CSV, manual rosters) are rejected here — use POST /campaigns/audience/preview for those instead.

Headers
Stripe-style idempotency token. Pass a stable, client-generated value (1-255 chars) to dedupe retries on transient timeouts. The same key+credential+path replays the original response for 24h on 2xx (5min on 4xx, 30s on 5xx). Returns 409 if a concurrent request with the same key is already in flight; replayed responses include the Idempotency-Replay: true response header.
1 - 255Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.

Provider container reference (list/report/filter id, or the CDP account group_id). Required unless type is orbit_segment.
