What changed

The daily_outcomes_curve, budget_guardrail and estimate_dau fields are removed from GET /{ad-account-id}/delivery_estimate and GET /{adset-id}/delivery_estimate responses because the service behind them was shut down. The removal applies to Marketing API v26.0 and to all remaining versions on 2026-10-27; the calls still succeed but the fields are missing.

What to do

Stop requesting and reading daily_outcomes_curve, budget_guardrail and estimate_dau; treat them as absent. Meta offers no replacement, so remove any forecasting or budget UI that depends on them or derive it from the remaining estimate fields.
