8X8 Rate Limits

8x8 publishes rate limits per API suite, not platform-wide, and the two suites signal throttling differently. The Connect/CPaaS messaging platform runs very high per-subaccount and per-IP request ceilings with no daily quota and signals only with Retry-After. The Administration API Suite (beta) runs a much tighter per-API-key budget and emits the x-ratelimit-* header family. Client-IP rate limiting is an opt-in anti-fraud control on three CPaaS endpoints.

8X8 Rate Limits is the machine-readable rate-limit profile for 8x8 on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 7 rate-limit definitions, measuring requests_per_second, requests_per_day, messages_per_request, requests_per_minute, and requests_per_window.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting, CPaaS, Contact Center, and Messaging.
