latestOpenAPI 3.1.02026-08-075421692.0 MBCreate a Reach & Frequency prediction
Creates an R&F prediction — a QUOTE, nothing is bought and no ad entities are created. Provide a date range plus exactly one of budgetAmount (Meta predicts reach) or reach (Meta predicts the budget). The response carries the estimate and its allowed bounds (min/max budget and reach). Predictions expire on their own; to buy, reserve one via POST /v1/ads/rf-predictions/{predictionId}/reserve and pass the RESERVED id to POST /v1/ads/create with buyingType: "RESERVED".
Reservation campaigns reject automatic placements. Top-level placements wins; when it is omitted, targeting.placements is used; when neither is set, placements default to Facebook feed (+ Instagram stream when a linked IG professional account resolves). Instagram placements require that IG account.
