Ringcentral Rate Limits

RingCentral applies per-user, per-application rate limits to every REST API call. Each operation is bucketed into one of four categories — Light, Medium, Heavy, or Auth — each with its own per-minute quota. Exceeding a quota returns HTTP 429 with a Retry-After header. Default per-app limits can be raised via the Developer Console for production-graded apps.

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

It captures 4 rate-limit definitions, measuring requests.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Communications, UCaaS, Voice, Video, and Contact Center.

Policies

Backoff Strategy
Clients must implement exponential backoff with jitter and honor the Retry-After header. Apps should also respect category-specific quotas by inspecting the X-Rate-Limit-* headers returned on every response.
App Graduation
Apps in sandbox have lower defaults than production. After graduation through the Developer Console, an app receives the standard production quotas above; further increases are negotiated with RingCentral.
