# Get engagement fixed audience samples

`POST https://api.gleap.io/v3/engagements/{engagementId}/fixed-audience-samples`

Estimate the fixed audience of an engagement. Send `targetAudience` and `conditions` in the body to preview a candidate audience without saving it. `csvContacts` may be sent as well: an object with `sessionIds` previews that (possibly unsaved) uploaded list, `null` previews the rules-based audience, and omitting it uses the stored list. Returns `{ sample, count, limitReached, limit }`.

## Authorization

- `Authorization` (header, required): `Bearer <token>`
