Mgid Rate Limits

MGID publishes no rate limits for any of its three REST APIs — no requests-per-second or per-day ceiling, no rate-limit response headers, no Retry-After, and no documented status code on exhaustion. What MGID does publish are per-request volume constraints: page-size ceilings that differ per endpoint (500 campaigns, 1,000 report rows on the advertiser surface, 100,000 rows on the publisher surface) and a 90-day maximum reporting window. Those are captured below because they are the only published throughput controls a client can plan against.
