Meta API 429 means your app or ad account exceeded throughput limits. Learn to throttle writes and use usage headers safely.
Meta API 429 indicates your integration exceeded app, user, or ad-account rate limits. Read Meta usage headers, reduce parallel writes, and retry with exponential backoff. Prioritize idempotent retries for create/update operations and queue non-critical calls.
