8x8 · Rate Limits

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, in the API Commons Rate Limits shape.

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

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled.

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